> Subject: [Intel-wired-lan] [PATCH v2 intel-net 2/2] ice: parametrize functions
> responsible for Tx ring management
>
> Commit ae15e0ba1b33 ("ice: Change number of XDP Tx queues to match
> number of Rx queues") tried to address the incorrect setting of XDP queue
> count that was based on the Tx queue count, whereas in theory we should
> provide the XDP queue per Rx queue. However, the routines that setup and
> destroy the set of Tx resources are still based on the
> vsi->num_txq.
>
> Ice supports the asynchronous Tx/Rx queue count, so for a setup where
> vsi->num_txq > vsi->num_rxq, ice_vsi_stop_tx_rings and ice_vsi_cfg_txqs
> will be accessing the vsi->xdp_rings out of the bounds.
>
> Parametrize two mentioned functions so they get the size of Tx resources
> array as the input.
