Hi Nicolas,
thanks a lot for your patch.

Like all other network functions, let's notify gtp

While this may be in-line with typical kernel tunnel device practises, I am not
convinced it is the right way to go for GTP.
Contrary to other tunneling mechansims, GTP doesn't have a 1:1 rlationship between
tunnels and netdev's. You can easily have tens of thousands - or even many more -
PDP contexts (at least one per subscriber) within one "gtp0" netdev. Also, the
state
is highly volatile. Every time a subscriber registers/deregisters, goes in or out of
coverage, in or out of airplane mode, etc. those PDP contexts go up and down.
Sending (unsolicited) notifications about all of those seems quite heavyweight to me.
