I think it would be better to be more general and support a vif-post.d
style directory which can contain scripts all of which are called (with
a defined set of paramters/env variables).

Not sure if we want vif-{route,bridge,etc}-post.d or not, perhaps that's
overkill. Using -post.d leaves open the option to add -pre.d in the
future as necessary.

Seems like a reasonable enough idea to me, please send a patch though.
