7   mac80211 provides its own workqueue for drivers and internal mac80211 use.
8   The workqueue is a single threaded workqueue and can only be accessed by
9   helpers for sanity checking. Drivers must ensure all work added onto the
10   mac80211 workqueue should be cancelled on the driver <code class="function">stop</code> callback.
11   </p><p>
12   mac80211 will flushed the workqueue upon interface removal and during
13   suspend.
14   </p><p>
15   All work performed on the mac80211 workqueue must not acquire the RTNL lock.
