The new command (NCSI_CMD_SEND_CMD) is added to allow user space application
to send NC-SI command to the network card.
Also, add a new attribute (NCSI_ATTR_DATA) for transferring request and
response.
The work flow is as below.
Request:
User space application
-> Netlink interface (msg)
-> new Netlink handler - ncsi_send_cmd_nl()
-> ncsi_xmit_cmd()
Response:
Response received - ncsi_rcv_rsp()
-> internal response handler - ncsi_rsp_handler_xxx()
-> ncsi_rsp_handler_netlink()
-> ncsi_send_netlink_rsp ()
-> Netlink interface (msg)
-> user space application
Command timeout - ncsi_request_timeout()
-> ncsi_send_netlink_timeout ()
-> Netlink interface (msg with zero data length)
-> user space application
Error:
Error detected
-> ncsi_send_netlink_err ()
-> Netlink interface (err msg)
-> user space application
