>Subject: [Intel-wired-lan] [PATCH iwl-net 1/3] ice: remove af_xdp_zc_qps
>bitmap
>
>Referenced commit has introduced a bitmap to distinguish between ZC and
>copy-mode AF_XDP queues, because xsk_get_pool_from_qid() does not do
>this for us.
>
>The bitmap would be especially useful when restoring previous state after
>rebuild, if only it was not reallocated in the process. This leads to e.g.
>xdpsock dying after changing number of queues.
>
>Instead of preserving the bitmap during the rebuild, remove it completely and
>distinguish between ZC and copy-mode queues based on the presence of a
>device associated with the pool.
>
>Fixes: e102db780e1c ("ice: track AF_XDP ZC enabled queues in bitmap")
