I connected my PC to WL-500gP over a serial port and commented out
"config switch_vlan" section in a /etc/config/network file:
root@WL-500gP:~# cat /etc/config/network
config switch eth0
option enable 1
#config switch_vlan eth0_0
# option device "eth0"
# option vlan 0
# option ports "0 1 2 4 5"
#### Loopback configuration
config interface loopback
option ifname "lo"
option proto static
option ipaddr 127.0.0.1
option netmask 255.0.0.0
#### LAN configuration
config interface lan
option type bridge
option ifname "eth0"
option proto static
option ipaddr 192.168.1.1
option netmask 255.255.255.0
root@WL-500gP:~#
After a reload, the router was not reachable over the network.
Ifconfig output after commenting out the "config switch_vlan" section
was following:

Why is eth0.0 required? Is it related to how switch on this
platform(robo switch BCM5325) and OpenWRT internally work?
regards,
Martin
