net/ncsi: Add generic netlink family Add a generic netlink family for NCSI. This supports three commands; NCSI_CMD_PKG_INFO which returns information on packages and their associated channels, NCSI_CMD_SET_INTERFACE which allows a specific package or package/channel combination to be set as the preferred choice, and NCSI_CMD_CLEAR_INTERFACE which clears any preferred setting.

net/ncsi: Extend NC-SI Netlink interface to allow user space to send NC-SI command 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 Signed-off-by: Justin Lee <justin.lee1@dell.com> Reviewed-by: Samuel Mendoza-Jonas <sam@mendozajonas.com> Signed-off-by: David S.
