  Feb  4 2002	- created initially by ShuChen <shuchen@realtek.com.tw>.
  May 20 2002	- Add link status force-mode and TBI mode support.

 =========================================================================
   1. [DEPRECATED: use ethtool instead] The media can be forced in 5 modes.
 	 Command: 'insmod r8169 media = SET_MEDIA'
 	 Ex:	  'insmod r8169 media = 0x04' will force PHY to operate in 100Mpbs Half-duplex.

 	 SET_MEDIA can be:
  		_10_Half	= 0x01
  		_10_Full	= 0x02
  		_100_Half	= 0x04
  		_100_Full	= 0x08
