Linville" , Arik Nemtsov Subject: [PATCH v2 3/6] mac80211: add SSID for AP mode with change notification Date: Sun, 23 Jan 2011 23:02:56 +0200 Message-Id: <1295816579-28925-4-git-send-email-arik@wizery.com> In-Reply-To: <1295816579-28925-1-git-send-email-arik@wizery.com> References: <1295816579-28925-1-git-send-email-arik@wizery.com> Sender: linux-wireless-owner@vger.kernel.org List-ID: When operating as AP, save SSID data as part of the ieee80211_bss_conf struct. Allow low level drivers to receive notifications about SSID changes.
