Me too - but how do the upper parts of the stack select the link addr
to use? I.e. when pppoe calls the if_output function to enqueue a packet
on hme0 instead of tap0 - how does it tell hme0 to use a secondary
link address?

We could create an interface clone (say "hme0:1"), and have that do it's
own ether_ifattach(), while still using the same hardware.

But then we are back to a single, changable lladdr per interface.
