Subject: [PATCH 11/13] qtnfmac: add support for scan dwell time configuration
Date: Tue, 2 Oct 2018 09:26:07 +0000	[thread overview]
Message-ID: <20181002092542.18966-12-sergey.matyukevich.os@quantenna.com> (raw)
In-Reply-To: <20181002092542.18966-1-sergey.matyukevich.os@quantenna.com>

Firmware supports scan dwell time tuning for various types of scans.
Enable support for this feature:
- advertise capability to configure channel dwell time to host
- pass scan dwell parameters to wireless card in scan request
