FS#502 - Switch not configured on Asus RT-N12 B1 (brcm47xx)

----------
Followup from me and with a RT-N12D1 Router (D1 instead of B1) and Lede 17.01.2:
I believe all Asus RT-N12/16 have switched switch ports, I saw similar discussions on TomatoUsb/Shibby.
When installing a Lede firmware, on first start WAN and LAN1-3 ports are bridged, so if you are lucky behind another router this one will answer your dhcp request. I was able to ssh in with ipv6 local link, and then change vlans:
uci set network. at switch_vlan[0].ports='0 1 2 3 5t' # was '1 2 3 4 5t' before
uci set network. at switch_vlan[1].ports='4 5t' # was '0 5t' before
uci commit network
and after next reboot the switch did work as expected. This little change is all to make Asus RT-N1x routers happy (save the wireless problem on another issue)
