[v2,13/15] app/testpmd: support shared Rx queue for macswap fwd
Checks
Commit Message
From: Xiaoyu Min <jackmin@nvidia.com>
Add support of shared rxq.
If shared rxq is enabled, filter packet by stream according
to mbuf->port value and then fwd it in stream basis (as before).
If shared rxq is not enabled, just fwd it as usual in stream basis.
