Kernel errors in boot & an igmpproxy "issue" - mt7621

Ehlo wrtians!

Just wondering if these kernel errors actually indicate real issues. Googled quite a lot with no avail...

The odhcpd error only happens once, after boot. I reckon odhcp is started before networking is ready.

And another stupid question - would appreciate if anyone stumbled upon this "issue" could confirm it's a harmless warning:

That's the reason for option verbose 0

config igmpproxy
        option quickleave 1
        # option verbose [0-3](none, minimal[default], more, maximum)
        option verbose 0

config phyint
        option network wan
        option zone wan
        option direction upstream
        list altnet 192.168.1.0/24

config phyint
        option network lan
        option zone lan
        option direction downstream

I had to enable IGMP Snooping for br-lan and setup igmpproxy because of Google Hubs and Chromecat problems (unstable streaming, losing internet). Reckon that's what has to be done after reading this forum for quite a while...
