I think there is a standard define for that somewhere in include/linux
or maybe include/net.
But thinking about the big picture, i wonder why this is needed, at
least in a minimal implementation. Bit 0 is set in this MAC address,
so it is a L2 multicast frame. By default, all L2 multicast frames
should be delivered to the CPU. So it should work without this.
