Subject: [PATCH 20/20] iwlwifi: mvm: stop static queues correctly
Date: Fri, 8 Feb 2019 12:47:12 +0200 [thread overview]
Message-ID: <20190208104712.16210-21-luca@coelho.fi> (raw)
In-Reply-To: <20190208104712.16210-1-luca@coelho.fi>
From: Avraham Stern <avraham.stern@intel.com>
AP interfaces still use some static TX queues (for probes,
broadcast and multicast frames). These queues were not stopped
correctly when the transport layer indicated the queue should be
stopped. As a result, when flushing the queues, new frames from
the overflow queue were tx'd, so the queues still had frames after
flushing. This ended up in an assert since trying to remove a station
with non-empty queues.
Fix it by stopping the static queues correctly when required.
