Most likely, this is not enough, because for CAPP you really want to
know what sort of message. Just logging the fact that someone sent a
netlink message doesn't tell you anything about the network configuration
changes this entails.

Laus added a hook into rtnetlink to intercept the entire message. Doing
it inside the netlink dispatch routine was the best solution we found
because that's where you can tell whether it's rtnetlink (the other
families are less interesting), and you can easily match the message to
the result code.
