Subject: [PATCH v2] mac80211: notify NSS changed when IBSS and HT
Date: Wed, 17 Dec 2014 10:00:52 +0100	[thread overview]
Message-ID: <1418806852-558-1-git-send-email-janusz.dziedzic@tieto.com> (raw)

When using IBSS in HT mode, we always get NSS=1
in rc_update callback. Force NSS recalculation when
rates updated and notify driver that NSS changed.
