[PATCH 1/1] mac80211: sends HT IE to user level through wext

[Tomas Winkler <tomas.winkler@intel.com>]

From: Emmanuel Grumbach <emmanuel.grumbach@intel.com>

This patch adds HT IE in the scan list that is returned to user level
through wext. This is useful to let wpa_supplicant if a bss supports 11n or
not: WEP and TKIP are not supported in 11n.
