Transmit packet.

Parameters:

	iobuf	I/O buffer
	tcpip_protocol	Transport-layer protocol
	st_src	Source address, or NULL to use default
	st_dest	Destination address
	netdev	Network device (or NULL to route automatically)
	trans_csum	Transport-layer checksum to complete, or NULL

Return values:

rc

Return status code

This function takes ownership of the I/O buffer.
