Hi,

I'm facing a problem on an ALL5003 board with a RT5350:
(actual trunk r36813)

I've google around and saw this error on different platforms.
Is this a problem related to my (switch) config ?:

config interface 'loopback'
        option ifname 'lo'
        option proto 'static'
        option ipaddr '127.0.0.1'
        option netmask '255.0.0.0'

config globals 'globals'
        option ula_prefix 'fd60:3977:f07d::/48'

config switch
        option name 'switch0'
        option reset '1'
        option enable_vlan '0'

config interface 'lan'
        option ifname 'eth0'
        option type 'bridge'
        option proto 'static'
        option ipaddr '192.168.0.199'
        option netmask '255.255.255.0'
        option ip6assign '60'

I can see packets with tcpdump, but the board doesn't response
on 192.168.0.199.
