Hi Leon!

The only reason was that I was testing out the 16-bit char stuff that was 
discussed here a while ago. Also, 16-bit accesses are a bit faster than 8-bit 
on most CPUs (or am I wrong here?).

You definately have a point here. So you recommend going over to u8_t again? 

By the way, aren't there some kind of private MAC-addresses? I guess such an 
address should be the "default" address in the lwIP distribution files.

Great!
