Using net80211/IEEE80211_C_BITS macro

[Fehmi Noyan ISI]

Well, including ieee80211_var.h and attempting to compile the code throws dozens of error messages.


In addition, I wonder why IEEE80211_C_BITS is re-defined in ifieee80211.c.

Hi!

Uhm, we could totally break out more bits into separate header files
if including ieee80211_var.h doesn't work for you.

However, the capabilities macro, which is IEEE80211_C_BITS, is defined in sys/net80211/ieee80211_var.h and I am not sure whether #include'ing ieee80211_var.h just for this macro is a good idea or not.
