Subject: [PATCH V5 1/8] mac80211: propagate HE operation info into ieee80211_sta
Date:   Mon, 20 May 2019 10:55:01 +0200
Message-Id: <20190520085508.5888-2-john@phrozen.org>
In-Reply-To: <20190520085508.5888-1-john@phrozen.org>

MIME-Version: 1.0
Content-Transfer-Encoding: 8bit
Sender: linux-wireless-owner@vger.kernel.org
Precedence: bulk

Upon a successful assoc a station shall store the content of the HE
operation element inside ieee80211_sta so that the driver can setup the
hardware accordingly.
