[OpenWrt-Devel] [PATCH] ramips: revert failsafe switch workaround for RT5350 introduced in r42179.

[Vittorio G (VittGam)]

It is not needed anymore as TCP packets get passed correctly now even when VLAN is disabled.

This piece of code also broke routers where the LAN port is not wired to port 0 of the internal switch.
