+ This function checks to see if the driver specified by This supports the device specified by
+ ControllerHandle. Drivers will typically use the device path attached to
+ ControllerHandle and/or the services from the bus I/O abstraction attached to
+ ControllerHandle to determine if the driver supports ControllerHandle. This function
+ may be called many times during platform initialization. In order to reduce boot times, the tests
+ performed by this function must be very small, and take as little time as possible to execute. This
+ function must not change the state of any hardware devices, and this function must be aware that the
+ device specified by ControllerHandle may already be managed by the same driver or a
+ different driver. This function must match its calls to AllocatePages() with FreePages(),
+ AllocatePool() with FreePool(), and OpenProtocol() with CloseProtocol().
+ Because ControllerHandle may have been previously started by the same driver, if a protocol is
+ already in the opened state, then it must not be closed with CloseProtocol(). This is required
+ to guarantee the state of ControllerHandle is not modified by this function.
+
+ @param[in] This A pointer to the EFI_DRIVER_BINDING_PROTOCOL instance.
+ @param[in] ControllerHandle The handle of the controller to test. This handle
+ must support a protocol interface that supplies
+ an I/O abstraction to the driver.
+ @param[in] RemainingDevicePath A pointer to the remaining portion of a device path. This

+ The Response() function queues an HTTP response to this HTTP instance, similar to

+ The HTTP driver will queue a receive token to the underlying TCP instance. When data
+ is received in the underlying TCP instance, the data will be parsed and Token will
+ be populated with the response data. If the data received from the remote host

+
+ It is the responsibility of the caller to allocate a buffer for Body and specify the

Thanks Thomas, we will correct this typo when commit this patch.

+ The Response() function queues an HTTP response to this HTTP instance, similar to
+ Receive() function in the EFI TCP driver. When the HTTP request is sent successfully,
+ or if there is an error, Status in token will be updated and Event will be signaled.
+
+ The HTTP driver will queue a receive token to the underlying TCP instance. When data
+ is received in the underlying TCP instance, the data will be parsed and Token will
+ be populated with the response data. If the data received from the remote host
+ contains an incomplete or invalid HTTP header, the HTTP driver will continue waiting
+ (asynchronously) for more data to be sent from the remote host before signaling
+ Event in Token.
+
+ It is the responsibility of the caller to allocate a buffer for Body and specify the
+ size in BodyLength. If the remote host provides a response that contains a content
+ body, up to BodyLength bytes will be copied from the receive buffer into Body and
+ BodyLength will be updated with the amount of bytes received and copied to Body. This
+ allows the client to download a large file in chunks instead of into one contiguous
+ block of memory. Similar to HTTP request, if Body is not NULL and BodyLength is
+ non-zero and all other fields are NULL or 0, the HTTP driver will queue a receive
+ token to underlying TCP instance. If data arrives in the receive buffer, up to
+ BodyLength bytes of data will be copied to Body. The HTTP driver will then update
+ BodyLength with the amount of bytes received and copied to Body.
+
+ If the HTTP driver does not have an open underlying TCP connection with the host
+ specified in the response URL, Request() will return EFI_ACCESS_DENIED. This is
+ consistent with RFC 2616 recommendation that HTTP clients should attempt to maintain
+ an open TCP connection between client and host.

+ The Response() function queues an HTTP response to this HTTP instance, similar to
+ Receive() function in the EFI TCP driver. When the HTTP request is sent successfully,
+ or if there is an error, Status in token will be updated and Event will be signaled.
+
+ The HTTP driver will queue a receive token to the underlying TCP instance. When data
+ is received in the underlying TCP instance, the data will be parsed and Token will
+ be populated with the response data. If the data received from the remote host
+ contains an incomplete or invalid HTTP header, the HTTP driver will continue waiting
+ (asynchronously) for more data to be sent from the remote host before signaling
+ Event in Token.
+
+ It is the responsibility of the caller to allocate a buffer for Body and specify the
+ size in BodyLength. If the remote host provides a response that contains a content
+ body, up to BodyLength bytes will be copied from the receive buffer into Body and
+ BodyLength will be updated with the amount of bytes received and copied to Body. This
+ allows the client to download a large file in chunks instead of into one contiguous
+ block of memory. Similar to HTTP request, if Body is not NULL and BodyLength is
+ non-zero and all other fields are NULL or 0, the HTTP driver will queue a receive
+ token to underlying TCP instance. If data arrives in the receive buffer, up to
+ BodyLength bytes of data will be copied to Body. The HTTP driver will then update
+ BodyLength with the amount of bytes received and copied to Body.
+
+ If the HTTP driver does not have an open underlying TCP connection with the host
+ specified in the response URL, Request() will return EFI_ACCESS_DENIED. This is
+ consistent with RFC 2616 recommendation that HTTP clients should attempt to maintain
+ an open TCP connection between client and host.

+ The Response() function queues an HTTP response to this HTTP instance, similar to

+
+ The HTTP driver will queue a receive token to the underlying TCP instance. When data
+ is received in the underlying TCP instance, the data will be parsed and Token will
+ be populated with the response data. If the data received from the remote host
+ contains an incomplete or invalid HTTP header, the HTTP driver will continue waiting
+ (asynchronously) for more data to be sent from the remote host before signaling
+ Event in Token.
+
+ It is the responsibility of the caller to allocate a buffer for Body and specify the

+ body, up to BodyLength bytes will be copied from the receive buffer into Body and
+ BodyLength will be updated with the amount of bytes received and copied to Body. This
+ allows the client to download a large file in chunks instead of into one contiguous

+ non-zero and all other fields are NULL or 0, the HTTP driver will queue a receive
+ token to underlying TCP instance. If data arrives in the receive buffer, up to

+ ControllerHandle. Drivers will typically use the device path attached to
+ ControllerHandle and/or the services from the bus I/O abstraction attached to
+ ControllerHandle to determine if the driver supports ControllerHandle. This function
+ may be called many times during platform initialization. In order to reduce boot times, the tests
+ performed by this function must be very small, and take as little time as possible to execute. This
+ function must not change the state of any hardware devices, and this function must be aware that the
+ device specified by ControllerHandle may already be managed by the same driver or a
+ different driver. This function must match its calls to AllocatePages() with FreePages(),
+ AllocatePool() with FreePool(), and OpenProtocol() with CloseProtocol().
+ Because ControllerHandle may have been previously started by the same driver, if a protocol is
+ already in the opened state, then it must not be closed with CloseProtocol(). This is required
+ to guarantee the state of ControllerHandle is not modified by this function.

+ The Response() function queues an HTTP response to this HTTP instance, similar to
+ Receive() function in the EFI TCP driver. When the HTTP request is sent successfully,
+ or if there is an error, Status in token will be updated and Event will be signaled.
+
+ The HTTP driver will queue a receive token to the underlying TCP instance. When data
+ is received in the underlying TCP instance, the data will be parsed and Token will
+ be populated with the response data. If the data received from the remote host
+ contains an incomplete or invalid HTTP header, the HTTP driver will continue waiting
+ (asynchronously) for more data to be sent from the remote host before signaling
+ Event in Token.
+
+ It is the responsibility of the caller to allocate a buffer for Body and specify the
+ size in BodyLength. If the remote host provides a response that contains a content
+ body, up to BodyLength bytes will be copied from the receive buffer into Body and
+ BodyLength will be updated with the amount of bytes received and copied to Body. This
+ allows the client to download a large file in chunks instead of into one contiguous
+ block of memory. Similar to HTTP request, if Body is not NULL and BodyLength is
+ non-zero and all other fields are NULL or 0, the HTTP driver will queue a receive
+ token to underlying TCP instance. If data arrives in the receive buffer, up to
+ BodyLength bytes of data will be copied to Body. The HTTP driver will then update
+ BodyLength with the amount of bytes received and copied to Body.
+
+ If the HTTP driver does not have an open underlying TCP connection with the host
+ specified in the response URL, Request() will return EFI_ACCESS_DENIED. This is
+ consistent with RFC 2616 recommendation that HTTP clients should attempt to maintain
+ an open TCP connection between client and host.

+ The HTTP driver will queue a receive token to the underlying TCP instance. When data
+ is received in the underlying TCP instance, the data will be parsed and Token will
+ be populated with the response data. If the data received from the remote host
+ contains an incomplete or invalid HTTP header, the HTTP driver will continue waiting
+ (asynchronously) for more data to be sent from the remote host before signaling
+ Event in Token.
+
+ It is the responsibility of the caller to allocate a buffer for Body and specify the
+ size in BodyLength. If the remote host provides a response that contains a content
+ body, up to BodyLength bytes will be copied from the receive buffer into Body and
+ BodyLength will be updated with the amount of bytes received and copied to Body. This
+ allows the client to download a large file in chunks instead of into one contiguous
+ block of memory. Similar to HTTP request, if Body is not NULL and BodyLength is
+ non-zero and all other fields are NULL or 0, the HTTP driver will queue a receive
+ token to underlying TCP instance. If data arrives in the receive buffer, up to
+ BodyLength bytes of data will be copied to Body. The HTTP driver will then update
+ BodyLength with the amount of bytes received and copied to Body.
+
+ If the HTTP driver does not have an open underlying TCP connection with the host
+ specified in the response URL, Request() will return EFI_ACCESS_DENIED. This is
+ consistent with RFC 2616 recommendation that HTTP clients should attempt to maintain
+ an open TCP connection between client and host.

+ The Response() function queues an HTTP response to this HTTP instance, similar to
+ Receive() function in the EFI TCP driver. When the HTTP request is sent successfully,
+ or if there is an error, Status in token will be updated and Event will be signaled.
+
+ The HTTP driver will queue a receive token to the underlying TCP instance. When data
+ is received in the underlying TCP instance, the data will be parsed and Token will
+ be populated with the response data. If the data received from the remote host
+ contains an incomplete or invalid HTTP header, the HTTP driver will continue waiting
+ (asynchronously) for more data to be sent from the remote host before signaling
+ Event in Token.
+
+ It is the responsibility of the caller to allocate a buffer for Body and specify the
+ size in BodyLength. If the remote host provides a response that contains a content
+ body, up to BodyLength bytes will be copied from the receive buffer into Body and
+ BodyLength will be updated with the amount of bytes received and copied to Body. This
+ allows the client to download a large file in chunks instead of into one contiguous
+ block of memory. Similar to HTTP request, if Body is not NULL and BodyLength is

+ The Response() function queues an HTTP response to this HTTP instance, similar to
+ Receive() function in the EFI TCP driver. When the HTTP request is sent successfully,
+ or if there is an error, Status in token will be updated and Event will be signaled.
+
+ The HTTP driver will queue a receive token to the underlying TCP instance. When data
+ is received in the underlying TCP instance, the data will be parsed and Token will
+ be populated with the response data. If the data received from the remote host
+ contains an incomplete or invalid HTTP header, the HTTP driver will continue waiting
+ (asynchronously) for more data to be sent from the remote host before signaling
+ Event in Token.
+
+ It is the responsibility of the caller to allocate a buffer for Body and specify the
+ size in BodyLength. If the remote host provides a response that contains a content
+ body, up to BodyLength bytes will be copied from the receive buffer into Body and
+ BodyLength will be updated with the amount of bytes received and copied to Body. This
+ allows the client to download a large file in chunks instead of into one contiguous
+ block of memory. Similar to HTTP request, if Body is not NULL and BodyLength is
+ non-zero and all other fields are NULL or 0, the HTTP driver will queue a receive
+ token to underlying TCP instance. If data arrives in the receive buffer, up to
+ BodyLength bytes of data will be copied to Body. The HTTP driver will then update
+ BodyLength with the amount of bytes received and copied to Body.
+
+ If the HTTP driver does not have an open underlying TCP connection with the host
+ specified in the response URL, Request() will return EFI_ACCESS_DENIED. This is
+ consistent with RFC 2616 recommendation that HTTP clients should attempt to maintain
+ an open TCP connection between client and host.

+ The HTTP driver will queue a receive token to the underlying TCP instance. When data
+ is received in the underlying TCP instance, the data will be parsed and Token will
+ be populated with the response data. If the data received from the remote host
+ contains an incomplete or invalid HTTP header, the HTTP driver will continue waiting
+ (asynchronously) for more data to be sent from the remote host before signaling
+ Event in Token.
+
+ It is the responsibility of the caller to allocate a buffer for Body and specify the
+ size in BodyLength. If the remote host provides a response that contains a content
+ body, up to BodyLength bytes will be copied from the receive buffer into Body and
+ BodyLength will be updated with the amount of bytes received and copied to Body. This
+ allows the client to download a large file in chunks instead of into one contiguous
+ block of memory. Similar to HTTP request, if Body is not NULL and BodyLength is
+ non-zero and all other fields are NULL or 0, the HTTP driver will queue a receive
+ token to underlying TCP instance. If data arrives in the receive buffer, up to
+ BodyLength bytes of data will be copied to Body. The HTTP driver will then update
+ BodyLength with the amount of bytes received and copied to Body.
+
+ If the HTTP driver does not have an open underlying TCP connection with the host
+ specified in the response URL, Request() will return EFI_ACCESS_DENIED. This is
+ consistent with RFC 2616 recommendation that HTTP clients should attempt to maintain
+ an open TCP connection between client and host.

+ AllocatePool() with FreePool(), and OpenProtocol() with CloseProtocol().

+ Tests to see if this driver supports a given controller. If a child device is provided,

+ This function checks to see if the driver specified by This supports the device specified by
+ ControllerHandle. Drivers will typically use the device path attached to
+ ControllerHandle and/or the services from the bus I/O abstraction attached to
+ ControllerHandle to determine if the driver supports ControllerHandle. This function
+ may be called many times during platform initialization. In order to reduce boot times, the tests
+ performed by this function must be very small, and take as little time as possible to execute. This
+ function must not change the state of any hardware devices, and this function must be aware that the
+ device specified by ControllerHandle may already be managed by the same driver or a
+ different driver. This function must match its calls to AllocatePages() with FreePages(),
+ AllocatePool() with FreePool(), and OpenProtocol() with CloseProtocol().
+ Because ControllerHandle may have been previously started by the same driver, if a protocol is
+ already in the opened state, then it must not be closed with CloseProtocol(). This is required
+ to guarantee the state of ControllerHandle is not modified by this function.

+ parameter is ignored by device drivers, and is optional for bus
+ drivers. For bus drivers, if this parameter is not NULL, then
+ the bus driver must determine if the bus controller specified

+ The HTTP driver will queue a receive token to the underlying TCP instance. When data
