[PATCH] Fix RTNLGRP definitions in rtnetlink.h

[Kristian Slavov]

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.

Cheers,
