Hi,
The subject says it all. I'm trying to do this for people who would like to
take advantage of net80211 on -8 so they don't have to upgrade to get newer
stuff.
(And so I can leave my netbook at -8 and not have to upgrade.)
Here's what I've done so far to get a module to build. I'd like to try and
commit whatever's needed to get it to build without too much evilness.
Firstly, I needed to move /usr/src/sys/net80211 out of the way, as the
include's are #include <net80211/ieee80211_X.h> and the search path is:
cc -O2 -pipe -fno-strict-aliasing -Werror -D_KERNEL -DKLD_MODULE -nostdinc
-I. -I@ -I@/contrib/altq ...
.. and this obviously isn't any good for what needs to happen here. I wonder
if it's possible to modify the early include path to include -I../.. so the
correct net80211 headers are included.
The patches so far:
