These patches should not be backported to OpenWrt, otherwise tproxy
won't work for devices connected to br-lan (bypassed by the fw rules).
We have introduced a new compile-time flag for new version (which
is not released yet), but it's unnecessray to backport redudant
patches as here is still at the old version.
Fixes: #1042
