DWA 123 bone support

Hi guys,
I installed the linux wireless tar file and then untarred it and ran the make command.
However it tells me :
“WARNING: CONFIG_CFG80211
_WEXT will be deactivated or not working because kernel was compiled with CONFIG
_WIRELESS_EXT=n. Tools using wext interface like iwconfig will not work. To acti
vate it build your kernel e.g. with CONFIG_LIBIPW=m.”

I would have to build my own kernel just for enabling wireless support? If so what the easiest way to do it ?
