   *	802.3 isn't really a protocol data link layer. Some old IPX stuff
   *	uses it however. Note that there is only one 802.3 protocol layer
   *	in the system. We don't currently support different protocols
   *	running raw 802.3 on different devices. Thankfully nobody else
   *	has done anything like the old IPX.
