[lwip-devel] [bug #26309] Implement SOF_BROADCAST

[Simon Goldschmidt]

Follow-up Comment #14, bug #26309 (project lwip):

On lwip-devel, Stéphane Lesage brought up this link:

plus:

Isn't that a bit unportable: your socket would get unusable if the interface
address changed...

However, the opengroup documentation seems to say the contrary of what's
implemented in linux *and* windows. I really don't know what's the best thing
to do here, but normally I'd vote for the opengroup definition...
