I spent a bunch of time over the weekend trying to debug that very 
problem, but the mailing list was down so I couldn't post about it.  If 
you look at the hex dumps long enough, you'll realize that every byte in 
each packet is 14 bytes before where it should be.  I suspect it's a 
problem in the writing of the Ethernet headers, but I have no idea how 
I'd fix it.  I guess I'll wait for the next patch.
