Manul build Atheros AR8151 for ArchLinux

Well... This also take me couple hours. It shouldn't' be. So I need to note it for myself.

First, there is not build-in support for atheros AR8151 ethernet chip in archlinux. You need to build it by yourself.

1.Download driver from http://partner.atheros.com/Drivers.aspx

2.extract tar ball to somewhere.

3.make sure you have related package like gcc, make, kernel header.

4.The driver from atheros default take /lib/modules/$(BUILD_KERNEL)/build for kernel header and I change to /usr/src/linux-$(BUILD_KERNEL) by change the order of KSP variable in src/Makefile

5.Refer to readme file in tar ball, I found I don't have version.h in header path and do "make include/linux/version.h" in linux source tree.

6.I use kernel 2.6.33 and it seems have a change which not use utsrelease.h file. But the driver makefile need it. I manually add a utsrelease.h in /usr/src/$(KERNEL_VERSION)/include/linux with content "#define UTS_RELEASE 2.6.33-ARCH"

7.build driver with "make" and "make install" to install it (don't forget install as root)

8.You should get a driver as kernel module in /lib/modules//kernel/drivers/net/atl1e/atl1e.ko. The readme file of tar ball show it as arl1e.ko but I get alt1e.ko. I don't know why but it don't matter. It's the driver for AS8151.

9.load the driver by "modprobe atl1e" and check it with "lsmod | grep atl1e"

10.Finish to build driver. You can test it by "ifconfig ethx

Then the AR5181 ethernet chip works. And don't forget to add it to MODULE of /etc/rc.conf or config modprobe for next boot.
