Subject: [PATCH net-next 0/4] i40e driver performance tweaks for AF_XDP
Date: Thu, 2 Jul 2020 17:37:26 +0200 [thread overview]
Message-ID: <20200702153730.575738-1-bjorn.topel@gmail.com> (raw)
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, xsk: remove HW descriptor prefetch in AF_XDP path
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
