Setting HT capabilities in net80211

[Alexander Egorenkov]

There are already constants defined in iee80211.h.
E.g. IEEE80211_HTCAP_MCSFBACK_UNSOL.

But the problem is that e.g. IEEE80211_HTCAP_MCSFBACK_UNSOL is equal to
0x0200
and the capabilty constant IEEE80211_HTCAP_RXSTBC_2STREAM has the same
value.
So we cannot use ic_htcap field for both capabilities because they will
overwrite each other.

But  we can add a new field to ieee80211com struct like ic_htextcaps where
all the extended
HT capabilities can be set. And this new field can be checked in function
ieee80211_add_htcap_body.

Another option is to change the value of IEEE80211_HTCAP_MCSFBACK_UNSOL and
all other extended capability constant which conflict with normal HT
capability constants.

Or do you have any other ideas ?
