(In reply to Allan Jude from comment #1)
It's related in that it touched the line of code at which we're crashing, but
without the change that bcopy was bogus: lle->ll_addr is a char *, so
bcopy(&lle->ll_addr, LLADDR(sdl), ifp->if_addrlen) just copies the address
of the MAC address into sdl, rather than the MAC address itself. The type
of lle->ll_addr changed in r292978.

Based on the panic, lle->ll_addr is NULL in your case.

Did this start occurring after an update? What was the from-revision?
