net/ncsi: NCSI command packet handler
The NCSI command packets are sent from MC (Management Controller) to remote end. They are used for multiple purposes: probe existing NCSI package/channel, retrieve NCSI channel's capability, configure NCSI channel etc. This defines struct to represent NCSI command packets and introduces function ncsi_xmit_cmd(), which will be used to transmit NCSI command packet according to the request. The request is represented by struct ncsi_cmd_arg. Signed-off-by: Gavin Shan <gwshan@linux.vnet.ibm.com> Acked-by: Joel Stanley <joel@jms.id.au> Signed-off-by: David S. Miller <davem@davemloft.net>
