The following patch is an example of a userspace tools (in fact, iptables)
that use the new netlink API to monitor tables activity.

I will also send a patch against libnfnetlink to update linux includes with
this new feature.

Maybe another API can be used for this feature: adding a setsockopt() on an
iptc socket to enable monitoring. When a table is updated, a packet (built with
CMSG_* macro for example) can be sent over all sockets that monitor tables
acitivity (like km sockets in IPsec). I know that this socket was used only with
[g|s]etsockopt(), but this can avoid adding another netlink API.

Comments are welcome.
Any feedback about this patch or the other proposed API?


Regards,
Nicolas
