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 phy affinity item in rte flow API, and the phy affinity value reflects the physical phy affinity of the received packets. This patch adds the tx_phy_affinity setting in Tx queue API, the affinity value reflects packets be sent to which hardware 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. RFC: http://patches.dpdk.org/project/dpdk/cover/20221221102934.13822-1-jiaw...@nvidia.com/ The PMD patch will be sent soon.
