Subject[PATCH AUTOSEL 4.9 41/48] nl80211: always accept scan request with the duration set
Date
From: Avraham Stern <avraham.stern@intel.com>

[ Upstream commit c837cbad40d949feaff86734d637c7602ae0b56b ]

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.
