|
|
* 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.
