It's the normal default.
Use openprom setting 'local-mac-address?' to toggle whether you want them
to all share a MAC, or use the individual MAC on the cards themselves.
Note that some hardware (I believe Foundry Networks equipment falls into
this category) cannot live with the card set one way or the other
regardless of where the cables end up being plugged into.
