>Tx
>queues when stopping rings
>
>Seth reported that on his side XDP traffic can not survive a round of down/up
>against i40e interface. Dmesg output was telling us that we were not able to
>disable the very first XDP ring. That was due to the fact that in
>i40e_vsi_stop_rings() in a pre-work that is done before calling
>i40e_vsi_wait_queues_disabled(), XDP Tx queues were not taken into the
>account.

>To fix this, let us distinguish between Rx and Tx queue boundaries and take
>into
>the account XDP queues for Tx side.
