10GbE Intel Wired LAN Driver Updates 2021-12-28

Alexander Lobakin says:

napi_build_skb() I introduced earlier this year ([0]) aims
to decrease MM pressure and the overhead from in-place
kmem_cache_alloc() on each Rx entry processing by decaching
skbuff_heads from NAPI per-cpu cache filled prior to that by
napi_consume_skb() (so it is sort of a direct shortcut for
free -> mm -> alloc cycle).
Currently, no in-tree drivers use it. Switch all Intel Ethernet
drivers to it to get slight-to-medium perf boosts depending on
the frame size.

ice driver, 50 Gbps link, pktgen + XDP_PASS (local in) sample:

frame_size/nthreads  64/42  128/20  256/8  512/4  1024/2  1532/1

net-next (Kpps)      46062  34654   18248  9830   5343    2714
series               47438  34708   18330  9875   5435    2777
increase             2.9%   0.15%   0.45%  0.46%  1.72%   2.32%

Additionally, e1000's been switched to napi_consume_skb() as it's
safe and works fine there, and there's no point in napi_build_skb()
without paired NAPI cache feeding point.
