Subject: [PATCH 2/3] ath11k: add software monitor ring descriptor for full monitor
Date: Wed, 21 Jul 2021 20:19:04 +0300	[thread overview]
Message-ID: <20210721171905.61838-3-jouni@codeaurora.org> (raw)
In-Reply-To: <20210721171905.61838-1-jouni@codeaurora.org>

From: Anilkumar Kolli <akolli@codeaurora.org>

In full monitor mode, monitor destination ring is read in
software monitor ring descriptor format instead of
reo_entrance_ring format. Add new sw_mon_ring descriptor.

Tested-on: QCN9074 hw1.0 PCI WLAN.HK.2.4.0.1-01734-QCAHKSWPL_SILICONZ-1
