Looks like the current code isn't taking care of a possible changing
of IFF_BROADCAST. I can find some code in net/core/dev.c to handle
MULTICAST or PROMISC but nothing for BROADCAST.
do I have to implement one ?

Looks like I need then to add a .ndo_change_rx_flags function to
manage this changes.

Does someone confirm this is the way to go ?
