Just FYI, you're racing with Nvidia adding netmem support to mlx5 as
well. Probably they prefer to take their patch. So try to rebase on
top of that maybe? Up to you.

I also wonder if you should send this through the net-next tree, since
it seem to race with changes that are going to land in net-next soon.
Up to you, I don't have any strong preference. But if you do send to
net-next, there are a bunch of extra rules to keep in mind:
