<Linux device driver for Realtek Ethernet controllers>

  This is the Linux device driver released for RealTek Ethernet controllers, which are listed as following.
	1. RTL8169S/SB/SC (Gigabit Ethernet with PCI interface)
	2. RTL8168B (Gigabit Ethernet with PCI-Express interface)
	3. RTL8101E (Fast Ethernet with PCI-Express interface)

<Requirements>

  - kernel source tree (supported versions 2.4.x)
  - compiler/binutils for kernel compilation



<Quick install with proper kernel settings>

  Unpack the tarball :
	tar vzxf r1000_vX.YZ.tgz

  Change to the directory:
	cd r1000_vX.YZ

  If you are running the target kernel, then you should be
  able to do :

	make clean modules	(as root or with sudo)
	make install
	depmod -a




<Force Link Status>

1. Force the link status when insert the driver.
	If the user is in the path ~/r1000, the link status can be forced to one of the 5 modes as following command.

	#insmod ./src/r1000.o speed=SPEED_MODE duplex=DUPLEX_MODE autoneg=NWAY_OPTION

	,where
		SPEED_MODE	= 1000	for 1000Mbps
				= 100	for 100Mbps
				= 10	for 10Mbps
		DUPLEX_MODE	= 0	for half-duplex
				= 1	for full-duplex
		NWAY_OPTION	= 0	for auto-negotiation off
				= 1	for auto-negotiation on
	For example:
	#insmod ./src/r1000.o speed=100 duplex=0 autoneg=0
	will force PHY to operate in 100Mpbs Half-duplex.

2. Force the link status by using ethtool.
	a. Insert the driver first.
	b. Make sure that ethtool exists in /sbin.
	c. Make sure that the eth? is up. If eth? is not up, use the following commond.

	#ifconfig eth? up 

	d. Force the link status as the following command.

	#ethtool -s eth? speed SPEED_MODE duplex DUPLEX_MODE autoneg NWAY_OPTION

	,where
		SPEED_MODE	= 1000	for 1000Mbps
				= 100	for 100Mbps
				= 10	for 10Mbps
		DUPLEX_MODE	= half	for half-duplex
				= full	for full-duplex
		NWAY_OPTION	= off	for auto-negotiation off
				= on	for auto-negotiation on
