-  |  ---------	 ---------------------					     ---
-  |  05-May-99	 Created						     MKW
-  |  01-Jul-99	 Changed clock setting of sta_reg from 66Mhz to 50Mhz to
-  |		 better match OPB speed. Also modified delay times.	     JWB
-  |  29-Jul-99	 Added Full duplex support				     MKW
-  |  24-Aug-99	 Removed printf from dp83843_duplex()			     JWB
-  |  19-Jul-00	 Ported to esd cpci405					     sr
-  |  23-Dec-03	 Ported from miiphy.c to 440GX Travis Sawyer		     TBS
