Subject: [PATCH 08/14] qtnfmac: update bands information on CHANGE_INTF command
Date: Wed, 20 Mar 2019 10:04:00 +0000	[thread overview]
Message-ID: <20190320100340.14168-9-sergey.matyukevich.os@quantenna.com> (raw)
In-Reply-To: <20190320100340.14168-1-sergey.matyukevich.os@quantenna.com>

From: Igor Mitsyanko <igor.mitsyanko.os@quantenna.com>

In some regions, different regulatory limits (like max Tx power) may be
defined for different operating modes. As an example: in ETSI regions
DFS master devices may use higher transmit powers compared to DFS slave
devices. Update bands information in CHANGE_INTF command if mode of
operation changes.
