Add XDP support (w/o XSk yet) to the idpf driver using the libeth_xdp sublib, which will be then reused in at least iavf and ice. In general, nothing outstanding comparing to ice, except performance -- let's say, up to 2x for .ndo_xdp_xmit() on certain platforms and scenarios. libeth_xdp doesn't reinvent the wheel, mostly just accumulates and optimizes what was already done before to stop copying that wheel and the bugs over and over again. idpf doesn't support VLAN Rx offload, so only the hash hint is present for now.
