[RFC 0/5] add new port affinity item and affinity in Tx queue API

[Jiawei Wang]

For the multiple hardware ports connect to a single DPDK port (mhpsdp),
currently there is no information to indicate the packet belongs to
which hardware port.

This patch introduces a new port affinity item in rte flow API, and
the port affinity value reflects the physical port affinity of the
received packets.

The example of match the affinity item:
	testpmd> flow create 0 ingress group 0 pattern port_affinity affinity is 1 /
	end actions queue index 0 / end

This patch adds the tx_affinity setting in Tx queue API, the affinity value
reflects packets be sent to which hardware port.

The testpmd command format as below:
	testpmd> port config (port_id) txq (queue_id) affinity (value)

While uses the port affinity as a matching item in the flow, and sets the
same affinity on the tx queue, then the packet can be sent from the same
hardware port with received.

Jiawei Wang (5):
  ethdev: add port affinity match item
  ethdev: introduce the affinity field in Tx queue API
  drivers: add lag Rx port affinity in PRM
  net/mlx5: add port affinity item support
  drivers: enhance the Tx queue affinity
