This fix sets the basic rate set parameter for IBSS creator when the
basic rates are not explicitly specified in the user space.

Shouldn't cfg80211 do this?

Hi Johannes ,
Thank you for your suggestion,just found out ,i
think its already there to configure basic rates (if the user had not
expicitly specified the basic rates in user space) in the
nl80211_join_ibss(nl80211.c) , but the basic rates does not seems to get
set there.I had checked its status in mac80211 in function
ieee80211_ibss_join function , its still zero and I thought of calling
it there itself , but the basic rate was not properly set for 2Ghz, so
called it here and I had tested it ,and everything working fine.
Pleas correct me if I am wrong .
with thanks,
shafi

Well, I still think cfg80211 should do this, and it looks like it will
except when you use iwconfig. So are you using iw or iwconfig? If
iwconfig latter, you need to fix the wext code in cfg80211, if the
former you need to figure out where the information gets lost.

IBSS started from wireless extensions is currently
missing basic rate configuration, fix this by moving
the code to generate the default to the common code
that gets invoked for both nl80211 and wext.
