The main aim is to keep XDP metadata not only in case with build_skb(), but also when we do napi_alloc_skb() + memcpy(). All Intel drivers suffers from the same here: - metadata gets lost on XDP_PASS in legacy-rx; - excessive headroom allocation on XSK Rx to skbs; - metadata gets lost on XSK Rx to skbs. Those get especially actual in XDP Hints upcoming. I couldn't have addressed the first one for all Intel drivers due to that they don't reserve any headroom for now in legacy-rx mode even with XDP enabled. This is hugely wrong, but requires quite a bunch of work and a separate series. Luckily, ice doesn't suffer from that. igc has 1 and 3 already fixed in [0].
