[v2,07/15] app/testpmd: support shared Rx queues for IO forwarding
Checks
Commit Message
Supports shared Rx queue.
If shared Rx queue is enabled, group received packets by stream
according to mbuf->port value and then and forward in stream basis as
before.
If shared Rx queue is not enabled, just forward in stream basis.
