probably related to eth_type_trans not being called, or something else that
doesn't properly set skb2->nh.raw, I've experienced this while hacking on
802.2/NetBEUI, the message comes from net/core/dev.c, function
dev_queue_xmit_nit, line 882 in 2.4.9. I'll take a look now, but I'm in a
hurry, so don't hold your breath.
