Agreed not sure why you would ever want to do a late binding and
replace on a tc_mirred actions. But it is supported...

I will let Jamal teach you on this, /me is really tired of explaining
things to you John.

This was a meta-comment on the use case for doing this with mirred
action. Not necessarily about the patch itself.

I was actually curious where this happens in practice. The only thing
I can think of is your external logging box moved so you need to send
out another port. Is there any open source software that manages 'tc'
like this. If so I would like to read it.

So do you know of any?
