Hi,

I reported a problem and gave hints to the solution, but nobody seemed to
react. So I prepared a patch against 2.6.14.4.

Tested on 2.6.14.4 with "ip monitor addr" and with the program attached,
while adding and removing IPv6 address. Both programs didn't receive any
messages.
Tested 2.6.14.4 + this patch, and both programs received add and remove
messages.

Signed-off-by: Kristian Slavov <kristian.slavov@xxxxxxxxxxxxxx>

Cheers,
