=  Realtek 8139C/8139C+/8169S/8169SB/8169SC/8168B/8101E Driver for FreeBSD v4.x/5.x/6.0                     =
=================================================================================

This driver is modified by Realtek Semiconductor corp. and it has been tested OK
on FreeBSD 4.7, FreeBSD v5.1, FreeBSD v5.4, and FreeBSD v6.0. To update the driver, you may use method 1. If method 1 failed,
you must use method 2 which is more complex.

Method 1:
	1.Copy if_rl.ko in "modules" directory to "/modules" directory and overwrite 
	  the existing file.
	2.Modify the file "/boot/defaults/loader.conf" and set "if_rl_load" in "Network 
	  drivers" section to "Yes"
	3.Reboot.

Method 2:
	Because the FreeBSD kernel has default drivers to support RTL8139C and RTL8169S. To use the RTL8139C+, RTL8169SB, RTL8169SC, RTL8168B, and RTL8101E, you need to update your NIC driver by recompiling your FreeBSD kernel.

	The main steps you have to do:(FreeBSDSrcDir means the directory of FreeBSD source code
	and it may be "/usr/src/sys")

		1. keep the orginal driver source code:
			# cd /usr/src/sys/pci
			# cp if_rl.c if_rl.c.org
			# cp if_rlreg.h if_rlreg.h.org
			
			# cd /usr/src/sys/modules
			# cp Makefile Makefile.org
			
			# cd /usr/src/sys/modules/rl
			# cp Makefile Makefile.org
			
			# cd /usr/src/sys/i386/conf/
			# cp GENERIC GENERIC.org
			
		2. recompile your kernel	(you must install your FreeBSD source code first !!)
			# vim /usr/src/sys/i386/conf/GENERIC and delete rl and re
			# vim /usr/src/sys/modules/Makefile and delete rl and re
			# cd /usr/src/sys/i386/conf
			# /usr/sbin/config GENERIC
			
			(for FreeBSD 5.x/6.x)
			# cd ../compile/GENERIC
			(for FreeBSD 4.x)
			# cd ../../compile/GENERIC

			# make depend
			# make
			# make install
			# reboot
		
		3. update the driver source code:
		    Copy the dirver source code( if_rl.c and if_rlreg.h) into /usr/src/sys/pci
		    Copy the Makefile into /usr/src/sys/modules/rl
		    
		4. build the driver:
			# cd /usr/src/sys/modules/rl
			# make clean
			# make
		
		5. install the driver
			# cd /usr/src/sys/modules/rl
			# kldload ./if_rl.ko
			
		6. configurate the static IP address
			# ifconfig rl0 xxx.xxx.xxx.xxx
			
		7. configurate the IP address by DHCP
			# /sbin/dhclient rl0

	A:Change the definition of "OS_VER" in if_rlreg.h
