Be careful there, there is a reason why we don't allow this and this
has to do with support of multiple address filters... but here it
depends also what you mean with "use".

I need to admit, you can achieve the same behaviour of multiple user
space stacks and one monitor, _but_ you can easily filter the traffic
if you do it per interface...
