If all is done in one patch set, maybe is ok. But we have about 14 commits for
af-xdp. If that patch set includes these commits, then we will exceed 15
(net-next limits the commit number of one patch set).
I separated these patches from the final patch set because I think these commits
can exist independently even without af-xdp.
Whether the final xsk should use a separate file, we can look at it in future
patches. If you think we can merge it into one file, I am also OK with it.
Although other drivers currently use separate files.
So if you think this patch set itself is fine, then I hope we can merge this
first.
Thanks.
