 *      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.

 *      Place an 802.3 header on a packet. The driver will do the mac
 *      addresses, we just need to give it the buffer length.
