 *      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.
