Subject: [PATCH 01/12] nl80211: add basic multiple bssid support
Date: Thu, 4 Jun 2020 09:09:41 +0200 [thread overview]
Message-ID: <20200604070952.15481-2-john@phrozen.org> (raw)
In-Reply-To: <20200604070952.15481-1-john@phrozen.org>
This patch adds support for passing the multiple bssid config to the
kernel when adding an interface. A bss can be legacy, transmitting or
non-transmitting. A non-transmitting BSSID will have a parent interface,
which needs to be transmitting.
