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.

Sorry.
