Subject: [PATCH 09/31] iwlwifi: mvm: fix BT coex shared antenna activity check
Date: Sun,  1 Mar 2015 21:31:22 +0200	[thread overview]
Message-ID: <1425238304-498-9-git-send-email-emmanuel.grumbach@intel.com> (raw)
In-Reply-To: <1425238186.30202.5.camel@egrumbacBox>

From: Eyal Shapira <eyal@wizery.com>

The shared antenna should be forbidden to use only if there's
high BT activity. Comparing to BT_OFF was effectively causing
us to always forbid using the shared antenna for SISO. This
leads to degraded performance in scenarios where the shared
antenna would have better performance.
