I think it would make sense to Cc the netdev list at oss.sgi.com..

(and please inline the patch, makes it much easier to respond..)

Umm, in the kernel tree $Header$ and $Id$ will never be filled out.
Also empty changes comments are pretty useless.

Not needed in 2.4/2.5

This patch doesn't reference CONFIG_IPV6_MLD6_DEBUG anywhere else..

I can't see this actually beeing used anywhere..

This function would really benefit from use of the seq_file API..
