From ce7c9111a97492d04c504f40736a669c235d664a Mon Sep 17 00:00:00 2001 From: Kalle Valo Date: Thu, 18 Dec 2008 23:35:20 +0200 Subject: mac80211: track master queue status This is a preparation for the dynamic power save support. In future there are two paths to stop the master queues and we need to track this properly to avoid starting queues incorrectly. Implement this by adding a status array for each queue. The original idea and design is from Johannes Berg, I just did the implementation based on his notes. All the bugs are mine, of course.
