Ok, you might be onto something. It got = eliminated in 3.6.x; So I checked a few things with a cero-3.7.2-3 here:
=A0
#=A0ip maddr show | grep 224
shows nothing = (only ipv6 addresses show up for maddr)
=A0
Trying to start pimd shows:
pimd: 23:16:52.675= Cannot set PIM flag in kernel:(error 99): Protocol not available

Fixed that.
=A0
There is no /proc/net/igmp, but only /proc/= net/igmp6

I'm not sure what should be = shown nowadays for 224.X.

I mean, mdns-scan works. But cerowrt show= s no igmp
and an x86 box does.

uftpd doesn't work but hasn't ever work= ed.

fiddling...
=A0
=A0
Could this be Dave M's patch to remove routing cache or a= re we having .CONFIG misconfig?
=A0
Regards,
= Maciej
=A0
=A0

or perhaps I did something stupid regarding igmp. (is it even on?)
