Some programs require ability to accept packets destined to certain
MAC addresses (in addition to their own).
Example Jerome Ettienes vrrpd (

The trick is to add unicast addresses via SIOCADDMULTI and accept those
packets when they make their way up the stack.
I think this used to work, no? Donald, any history/comments behind
Patch attahced, not very well tested but looks safe.
