Subject: [PATCH net-next 00/13][pull request] idpf: add XDP support

Alexander Lobakin says:

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/...
