Add XDP support (w/o XSk for now) to the idpf driver using the libeth_xdp
sublib. All possible verdicts, .ndo_xdp_xmit(), multi-buffer etc. are here.
In general, nothing outstanding comparing to ice, except performance --
let's say, up to 2x for .ndo_xdp_xmit() on certain platforms and
scenarios.
idpf doesn't support VLAN Rx offload, so only the hash hint is
available for now.

Patches 1-7 are prereqs, without which XDP would either not work at all or
work slower/worse/...
Hi Alexander,

I'm wondering if you could give a hash that this patch-set applies to.
Or a branch where it has been applied.

I suspect it's terribly obvious how to do this, but I'm drawing a blank here.
I could've left `base-commit-id`, but Tony does rebasing of his trees
every day, so this wouldn't help at all.
Moreover, it's to be applied to Tony's next-queue, but not on top of it,
because currently there are patches in the tree that will go *after* my
series to net-next. So it's a bit complicated.
Thanks!
Thanks,
Olek
