I'm imagining from your statement that the in kernel code that
does this now doesn't manage this; I haven't checked.
My offhand feeling would be to pay 20 bytes of extra sockaddr_dl
to maintain the burned in address in core, and expose it to userland
as SIOCD*ADDR of the primary restoring the burned in (and maybe return
EFOOBAR if the primary is already the burned in).
