ice: xsk: Improve AF_XDP ZC Tx and use batching API
Apply the logic that was done for regular XDP from commit 9610bd98 ("ice: optimize XDP_TX workloads") to the ZC side of the driver. On top of that, introduce batching to Tx that is inspired by i40e's implementation with adjustments to the cleaning logic - take into the account NAPI budget in ice_clean_xdp_irq_zc(). Separating the stats structs onto separate cache lines seemed to improve the performance. Signed-off-by:Maciej Fijalkowski <maciej.fijalkowski@intel.com> Signed-off-by:
