Yeah, sorry, I already forgot about that :-)

Well, since netbufs are really only used for UDP (anyone using RAW 
pcbs?), I'd be OK with adding 'toadd' and 'toport' to netbufs 
(SOF_BROADCAST is really a different thing). However, for recvmsg(), 
we'd need packet headers, too, which would be another way for you to 
implement it.
