Subject: [PATCH net-next 0/4] i40e driver performance tweaks for AF_XDP

This series contains four patches worth of driver tweaks for the i40e
AF_XDP Rx path, that in total improves the Rx performance (rx_drop 64B
packets-per-second) with 17%.

Please refer to the individual commits for more details.


Cheers,
Björn

  i40e: use 16B HW descriptors instead of 32B
  i40e, xsk: increase budget for AF_XDP path
  i40e, xsk: move buffer allocation out of the Rx processing loop
