  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.

Introduce a new phy affinity item in rte flow API, and
the phy affinity value reflects the physical phy affinity of the
received packets.

Add the tx_phy_affinity setting in Tx queue API, the affinity value
reflects packets be sent to which hardware port.

Add the nb_phy_ports into device info and value greater than 0 mean
that the number of physical ports connect to the DPDK port.

While uses the phy 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.
