net: sk_pacing_shift_update() helper
In commit 3a9b76fd0db9 ("tcp: allow drivers to tweak TSQ logic")
I gave a code sample to set sk->sk_pacing_shift that was not complete.
Better add a helper that can be used by drivers without worries,
and maybe amended in the future.
A wifi driver might use it from its ndo_start_xmit()
Following call would setup TCP to allow up to ~8ms of queued data per
flow.
sk_pacing_shift_update(skb->sk, 7);
