> Add zero copy AF_XDP support. This patch adds zero copy support for Tx and
> Rx; code for zero copy is added to ice_xsk.h and ice_xsk.c.
>
> For Tx, implement ndo_xsk_wakeup. As with other drivers, reuse existing
> XDP Tx queues for this task, since XDP_REDIRECT guarantees mutual
> exclusion between different NAPI contexts based on CPU ID. In turn, a
> netdev can XDP_REDIRECT to another netdev with a different NAPI context,
> since the operation is bound to a specific core and each core has its own
> hardware ring.
>
> For Rx, allocate frames as MEM_TYPE_ZERO_COPY on queues that AF_XDP is
> enabled.
