This series contains improvements to the AF_XDP kernel infrastructure. They are required for the upcoming AF_XDP support in mlx5e, but also some of them benefit to all drivers, and some can be useful for other drivers that want to implement AF_XDP. ,
Maxim, Firstly; It's exciting to see Mellanox continuing to invest in XDP/BPF! Keep it up! I'll comment on the individual patches. Going forward, please rebase/tag the patches to bpf-next (and add the bpf mailing list). Cheers, Björn
