Topic: Compiling Broadcom ethernet drivers

[Des Dougan]

I'm setting up an IBM xSeries 205 server with 5.6. It came up fine after installation, but when I installed 5.6U5 and restarted the box, the network drivers (for Broadcom NetXtreme Gigabit cards) could no longer communicate with the hubs (old 3Com 100MB/s LinkBuilders, one emulating the outside world). The drivers load OK (checked via ifconfig), but I get no link light on the hub after networking starts (the lights come on as normal during boot). I restarted the box, and one worked, so I stopped and started network services, and both are not working again. I'm assuming something in the update has caused a problem with the tg3 driver, so I went to IBM's site and downloaded their latest BCM5700 driver source. However when I compile (I've installed Darrell May's compile tools on my test box for this), it failes with what looks like a path problem - mm.h:16:26: linux/config.h: No such file or directory

mm.h is an include in the b57um.c file. I've tried both the source RPM and the tarball, but get the same failure. I'm obviously missing something, but it's late, and my brain is locked up....

Can anyone give me a push in the right direction?

Thanks,

To close the loop on this, I resolved it. I realized that the compile tools contrib I'd downloaded had a different kernel sources RPM from the running kernel (2.4.18-3 instead of 2.4.18-5). After I'd downloaded the correct sources and installed the RPM, the make ran cleanly, and when I insmod'd the new driver, it worked right away, thankfully.
