> Subject: [Intel-wired-lan] [PATCH v2 intel-net 1/6] ice: xsk: return xsk buffers
> back to pool when cleaning the ring
>
> Currently we only NULL the xdp_buff pointer in the internal SW ring but we
> never give it back to the xsk buffer pool. This means that buffers can be
> leaked out of the buff pool and never be used again.
>
> Add missing xsk_buff_free() call to the routine that is supposed to clean the
> entries that are left in the ring so that these buffers in the umem can be used
> by other sockets.
>
> Also, only go through the space that is actually left to be cleaned instead of a
> whole ring.
