enic: provision for multiple Rx/Tx queues; prepare for RSS support
Provision for multiple Rx/Tx queues. Max of 8 WQs and 8 RQs. Max for completion queue is 8+8=16 and max for interrupt resources is 8+8+2. Add driver/firmware interface for setting up RSS secret key and indirection table. Signed-off-by: Scott Feldman <scofeldm@cisco.com> Signed-off-by: David S. Miller <davem@davemloft.net>
