Initial git repository build. I'm not bothering with the full history, even though we have it. We can create a separate "historical" git archive of that later if we want to, and in the meantime it's about 3.2GB when imported into git - space that would just make the early git days unnecessarily complicated, when we don't have a lot of good infrastructure for it. Let it rip!

* Address Layout:
|
|
* port address: physical MAC address
|
|
* 1st exact match: logical MAC address (GEnesis only)
|
|
* 2nd exact match: RLMT multicast (GEnesis only)
|
|
* exact match 3-13: OS-specific multicasts (GEnesis only)

* SK_INIT_IO
|
|
* ==========
|
|
*
|
|
* All permanent MAC addresses are read from EPROM.
|
|
* If the current MAC addresses are not already set in software,
|
|
* they are set to the values of the permanent addresses.
|
|
* The current addresses are written to the corresponding MAC.
