Feb 4 2002 - created initially by ShuChen <shuchen@realtek.com.tw>.
May 20 2002 - Add link status force-mode and TBI mode support.
=========================================================================
- 1. The media can be forced in 5 modes.
+ 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.
