[PATCH net-next 0/2] virtio-net: re enable XDP_REDIRECT for mergeable buffer
Hi:
This series tries to re-enable XDP_REDIRECT for mergeable buffer which
was removed since commit 7324f5399b06 ("virtio_net: disable
XDP_REDIRECT in receive_mergeable() case"). Main concerns are:
- not enough tailroom was reserved which breaks cpumap
- complex logic like EWMA and linearizing during XDP processing
Fix those by:
- reserve enough tailroom during refill
- disable EWMA
