Subject: [PATCH 1/5] iwlwifi: mvm: increase scan timeout to 20 seconds
Date: Fri, 10 Jun 2016 15:39:53 +0300	[thread overview]
Message-ID: <1465562397-1402-1-git-send-email-luca@coelho.fi> (raw)
In-Reply-To: <1465562195.29614.5.camel@coelho.fi>

From: Luca Coelho <luciano.coelho@intel.com>

The 16 seconds timeout we were using turned out to be too short.
Recalculations by system show that the total time in both bands should
be < 18.5 seconds, even in the slowest cases (e.g. DCM P2P with
DTIM=2).  Rounding it up to 20 seconds for a bit more safety.

Fixes: 728e825f81b1 ("iwlwifi: mvm: add a scan timeout for regular scans")
