By this I mean: we could benefit from a more general mechanism used to 
deal with link-layer addresses other than the hardware station address, 
perhaps kept in a hash table.

Some cards support more than one station address being set up with a 
perfect hash filter entry; I think fxp supports this. Perhaps Bill Paul 
knows more?
