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

I've tested it on my RT5350-based router. With a previous OpenWrt revision (r42649 if I remember well) it wasn't working, since it was zeroing a TCP field as seen from the tcpdump verbose output. I don't remember the tcpdump details correctly, sorry. But now with recent revisions it's working fine. If you're not sure about this for rt3x5x and mt7628, it should at least get modified to 0 1 2 3 4 5 6 to avoid soft-bricking routers where the only Ethernet port exposed is not 0 (4 for the HT-TM02 for instance).

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