The Inode field in /proc/net/{tcp,udp,packet,raw,...} is useful to know the types of 
file descriptors associated to a process. Actually lsof utility uses the field.
Unfortunately, unlike /proc/net/{tcp,udp,packet,raw,...}, /proc/net/netlink doesn't have the field.
This patch adds the field to /proc/net/netlink.

Unfortunately we cannot add new fields without breaking the parsing
done by existing applications.

Hmm we already did such expansion last year with commit 38938bfe when
Pablo Neira Ayuso added the Drops column

Extract of its Changelog :

 This patch also includes the use of sk_drop to account the number of
 netlink messages drop due to overrun. This value is shown in
 /proc/net/netlink.

So yes, some applications might break but they probably already broke
one year ago and their maintainers should know that adding new fields at
the end of lines is expected ?
