> To optimize datapath, the mlx5 pmd checked for mark action on flow

> actions), then it enabled the mark action logic only for flagged rxqs.
> 
> Mark action didn't work if no queue/rss action was in the same flow,
> even when the user use multi-group logic to manage the flows.
> So, if mark action is performed in group X and the packet is moved to group
> Y > X when the packet is forwarded to Rx queues, SW did not get the mark ID
> to the mbuf.
> 
> Flag Rx datapath to report mark action for any queue when the driver
> detects the first mark action after dev_start operation.
