Subject: [PATCH 6/7] mac80211: propagate spatial reuse info into ieee80211_sta
Date: Mon, 20 May 2019 13:02:03 +0200	[thread overview]
Message-ID: <20190520110204.27588-7-john@phrozen.org> (raw)
In-Reply-To: <20190520110204.27588-1-john@phrozen.org>

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