This patch adds initial support for XDP on e1000 driver. Note e1000
driver does not support page recycling in general which could be
added as a further improvement. However for XDP_DROP and XDP_XMIT
the xdp code paths will recycle pages.
This patch includes the rcu_read_lock/rcu_read_unlock pair noted by
Brenden Blanco in another pending patch.
net/mlx4_en: protect ring->xdp_prog with rcu_read_lock
Do you have any perf numbers of drops of this vs tc drop at ingress?
single or multiple cpus.
