backport-include: deal with struct sock::sk_pacing_shift
In kernel 4.15 the field sk_pacing_shift was introduced to allow
(wifi) drivers to change the behaviour of TSQ. In 4.16 a helper
function was added which mac80211 is using. So backport the helper
which is just a stub for kernels prior to 4.15.
