Subject: [PATCH v2] ath11k: Change qcn9074 fw to operate in mode-2
Date:   Wed,  8 Dec 2021 19:19:50 +0530
Message-Id: <1638971390-7160-1-git-send-email-akolli@codeaurora.org>
Precedence: bulk

From: Seevalamuthu Mariappan <seevalam@codeaurora.org>

In mode-2 QCN9074 firmware uses 15MB of host memory and firmware
request 1MB size segements in QMI, whereas in mode-0 firmware
uses 45MB of host memory and each segment is of 2MB size.
In mode-2 firmware operates with reduced number of vdevs and peers.

Tested-on: QCN9074 hw1.0 PCI WLAN.HK.2.4.0.1-01838-QCAHKSWPL_SILICONZ-1
