Should this paragraph above be a clue for the flag name?
Sorry for late comment, but having flag called FLAG_POINTTOPOINT is really
confusing. ptp, p2p terms are heavily used and will mislead folks.

Would it be better to call it something like IGNORE_MAC_ADDRESS if this is the
feature you are targeting?
