Log Message:
If the detected media is gigabit, change the gem to use GMII mode otherwise
switch back to MII mode.  Keep a sliding window for TX segments and when it
gets > 2/3 full, request a TX interrupt (window gets reset when the h/w TX
queue is empty).  Add dv_xname to a few printfs.  With the above changes,
the gem driver will now work on Macintoshes, even in GigE mode.  On a 733
PowerMac G4 it gets ~355Mb/s TX and ~280Mb/s RX to/from an Alpha XP1000.

XXX mii autoselect is still flakey.
