octeontx2-af: NIX AQ instruction enqueue support
Add support for a RVU PF/VF to submit instructions to NIX AQ via mbox. Instructions can be to init/write/read RQ/SQ/CQ/RSS contexts. In case of read, context will be returned as part of response to the mbox msg received. Signed-off-by: Sunil Goutham <sgoutham@marvell.com> Signed-off-by: David S. Miller <davem@davemloft.net>
