Subject: [RFC 7/8] cfg80211: ibss: use 11a mandatory rates for 6GHz band operation
Date:   Mon, 20 May 2019 14:00:44 +0200
Message-Id: <1558353645-18119-8-git-send-email-arend.vanspriel@broadcom.com>
In-Reply-To: <1558353645-18119-1-git-send-email-arend.vanspriel@broadcom.com>
References: <1558353645-18119-1-git-send-email-arend.vanspriel@broadcom.com>
Sender: linux-wireless-owner@vger.kernel.org
Precedence: bulk

The default mandatory rates, ie. when not specified by user-space, is
determined by the band. Select 11a rateset for 6GHz band.
