Porting Compat wireless driver for linux-2.6.21
 

I have compiled compat-wireless-2.6.32.16 for Atheros Ath9k wifi device corresponding to inux-2.6.21.
The following .ko s were only compiled :

cfg80211.k0
mac80211.ko
ath.ko
ath9k.ko

and the following 3 .ko s were not compiled

ath9k_hw.ko
ath9k_common.ko
compat.ko

As a result while i insert the compiled .kos I get a list of undefined symbols.

Please help.

Well, to start with you might be so kind as to show us what errors you got during compilation. You may also want to ask for this thread to be moved to the Kernel forum if you are really looking to port this code over yourself.
