10GbE Intel Wired LAN Driver Updates 2022-01-31
Alexander Lobakin says:
This is an interpolation of [0] to other Intel Ethernet drivers
(and is (re)based on its code).
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].
