Implement user-setable promiscuous mode (a new `promisc' flag for ifconfig(8)).
Also, for all interfaces in this mode pass all ethernet frames to upper layer,
even those not addressed to our own MAC, which allows packets encapsulated
in those frames be processed with packet filters (ipfw(8) et al).
