History:
Feb 4 2002 - created initially by ShuChen <shuchen@realtek.com.tw>.
May 20 2002 - Add link status force-mode and TBI mode support.
- 2004 - Massive updates. See kernel SCM system for details.
+ 2004 - Massive updates. See kernel SCM system for details.
=========================================================================
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
_1000_Full = 0x10
-

2. Support TBI mode.

VERSION 1.1 <2002/10/4>
The bit4:0 of MII register 4 is called "selector field", and have to be
00001b to indicate support of IEEE std 802.3 during NWay process of
