Log message:
unfortunately classful routing isn't 100% dead, mostly thanks to ancient
netboot methods using rarp, thus only learning their IP address without
mask. And of course the next step is a broadcast - which goes to the
broadcast address calculated classful. *sigh*. PR6382
instead of storing a second broadcast address per ifaddr as we used to
figure out wether we're dealing with a classful broadcast on the fly. the
math is extremely cheap and all my previous profilings showed that cpu
cycles are basically free, we're constrained by memory access.
excellent analysis by Pascal Lalonde <plalonde at overnet.qc.ca> who also
submitted the PR. claudio ok
