-Subject: [PATCH] ath9k: Fix MCC flush timeout
-
-In MCC mode, the duration for a channel context
-is half the beacon interval and having a large
-flush timeout will adversely affect GO operation,
-since the default value of 200ms will overshoot
-the advertised NoA absence duration.
-
-The scheduler initiates a channel context switch
-only when the slot duration for the current
-context expires, so there is no possibility of
-having a fixed timeout for flush.
-
-Since the channel_switch_time is added to the
-absence duration when the GO sets up the NoA
-attribute, this is the maximum time that we
-have to flush the TX queues. The duration is very
-small, but we don't have a choice in MCC mode.
