This a good idea and thank you for doing it. I like that the flag is expressed
as a positive value (rather than an inverse value like no-flood).

The name BR_UNICAST_FLOOD is too long, just use BR_FLOOD and keep the code
shorter.

This doesn't apply against current net-next (same problem as first patch).

Also, I am not a fan of having lots of boolean flag variables in normal
code paths. It ends up reading like PASCAL code. But probably unavoidable in this case.
