Eric Dumazet says:

====================
tcp: add three static keys

Recent addition of per TCP socket rx/tx cache brought
regressions for some workloads, as reported by Feng Tang.

It seems better to make them opt-in, before we adopt better
heuristics.

The last patch adds high_order_alloc_disable sysctl
to ask TCP sendmsg() to exclusively use order-0 allocations,
as mm layer has specific optimizations.
