Subject: [PATCH 4/8] rsi: change in device init frame sequence for 9116
Date:   Wed,  3 Apr 2019 09:43:05 +0530
Message-Id: <20190403041309.12829-5-siva8118@gmail.com>
In-Reply-To: <20190403041309.12829-1-siva8118@gmail.com>
References: <20190403041309.12829-1-siva8118@gmail.com>
Sender: linux-wireless-owner@vger.kernel.org
Precedence: bulk

Initial frame exchange sequence has been changed for 9116 chip. Getting MAC
address using EEPROM read frame will be once common device configuration is
done and RESET_MAC frame is sending after bootup parameters confirmation is
received, which are different from RS9113 device
