This series adds VF representors to the driver. It enables
single-queue representors and implements enough flow features to run
OVS-DPDK offload for default vlan+mac based switching.

The flow API handlers and devcmd functions (firmware commands) are now
aware of representors. Representors reserve PF Tx/Rx queues for their
implicit paths to/from VFs. Packet forwarding rules for these implicit
paths are set up using firmware's Flow Manager (flowman), which is
also used for rte_flow API.

Thanks.

Series applied to dpdk-next-net/main, thanks.
