[ipw2200-ap-devel] Compiling IPW2200 and IPW2200-ap

[Mike L. <nas...@co...>]

I would like to compile both ipw2200 and ipw2200-ap for use on an Intel ARM
system. I would only use one at a time. I repeat I would only use one at a
time. I can get both to compile, the ap module loads fine but when I try to
load the non-ap module it fails like this... 

FYI: I renamed the ipw2200-ap's ipw2200.c to be ipw2200-ap.c so I would not
get two modules with the same name.

Probably because the ieee80211 ieee80211_crypt are the ones compiled for the
ipw2200-ap, would the solution be to merge the ieee80211-1.1.12 that builds
a successful ipw2200 module with the ieee80211 sources in the ipw2200-ap
directory?

thanks for your time.
