@param This The protocol instance pointer.
|
|
@param HeaderSize The size, in bytes, of the media header to be filled in by
|
|
the Transmit() function. If HeaderSize is non-zero, then it
|
|
must be equal to This->Mode->MediaHeaderSize and the DestAddr
|
|
and Protocol parameters must not be NULL.
|
|
@param BufferSize The size, in bytes, of the entire packet (media header and
|
|
data) to be transmitted through the network interface.
|
|
@param Buffer A pointer to the packet (media header followed by data) to be
|
|
transmitted. This parameter cannot be NULL. If HeaderSize is zero,
|
|
then the media header in Buffer must already be filled in by the
|
|
caller. If HeaderSize is non-zero, then the media header will be
|
|
filled in by the Transmit() function.
|
|
@param SrcAddr The source HW MAC address. If HeaderSize is zero, then this parameter
|
|
is ignored. If HeaderSize is non-zero and SrcAddr is NULL, then
|
|
This->Mode->CurrentAddress is used for the source HW MAC address.
|
|
@param DestAddr The destination HW MAC address. If HeaderSize is zero, then this
|
|
parameter is ignored.
|
|
@param Protocol The type of header to build. If HeaderSize is zero, then this
|
|
parameter is ignored. See RFC 1700, section "Ether Types", for
|
|
examples.
|
|
|
|
@retval EFI_SUCCESS The packet was placed on the transmit queue.
|
|
@retval EFI_NOT_STARTED The network interface has not been started.
|
|
@retval EFI_NOT_READY The network interface is too busy to accept this transmit request.
|
|
@retval EFI_BUFFER_TOO_SMALL The BufferSize parameter is too small.
|
|
@retval EFI_INVALID_PARAMETER One or more of the parameters has an unsupported value.
|
|
@retval EFI_DEVICE_ERROR The command could not be sent to the network interface.

@retval EFI_UNSUPPORTED This function is not supported by the network interface.
