Subject: [PATCH 08/13] nl80211: always accept scan request with the duration set
Precedence: bulk

From: Avraham Stern <avraham.stern@intel.com>

Accept a scan request with the duration set even if the driver
does not support setting the scan dwell. The duration can be used
as a hint to the driver, but the driver may use its internal logic
for setting the scan dwell.
