I download wireless-testing git and found it looks
like linux kernel 2.6.27-rc8, or it is "kernel + 
mac80211 stack + kinds of wireless nic driver"?? 

I'm newer of it, and try to make menuconfig of it.
But there are so many errors like:
: command not
foundWPA_ath5k/wireless-testing/scripts/gcc-x86_64-has-stack-protector.sh:
line 2:
/home/wangyue/VLAN_WPA_ath5k/wireless-testing/scripts/gcc-x86_64-has-stack-protector.sh:
line 7: syntax error: unexpected end of file

Maybe the way I use it was not right.
Is there any docs on how to use it?
If it is a linux kernel, why make menuconfig was not
be
used?

Thanks in advance.
