9 * 802.3 isn't really a protocol data link layer. Some old IPX stuff
10 * uses it however. Note that there is only one 802.3 protocol layer
11 * in the system. We don't currently support different protocols
12 * running raw 802.3 on different devices. Thankfully nobody else
13 * has done anything like the old IPX.
