If you search the forum you'll probably find out why it can't be put into the firmware...Originally Posted by rdude
Anyway, I have another wish!
IPv4 IGMP support in the kernel! I... don't and probably will never use IGMP, it just bugs me knowing it's not there, especially because my ISP keeps automatically querying me about it (I see the V2 Membership Query packets with tcpdump) and the router doesn't reply. That's no big deal at all, but... why not have something that could probably be had at the expense of a few KB? I'm guessing ASUS took it out or commented something out to get rid of it for security purposes but I wouldn't mind it just being there even if I didn't use it. I mean, there's /proc/net/igmp6 but not /proc/net/igmp ...
So that's that.
