Subject: [PATCH RFC 7/8] ath11k: Add multi TX ring support for WCN6750
Date:   Thu, 27 Jan 2022 11:03:28 +0530
Message-ID: <1643261609-13500-8-git-send-email-quic_mpubbise@quicinc.com>
In-Reply-To: <1643261609-13500-1-git-send-email-quic_mpubbise@quicinc.com>
References: <1643261609-13500-1-git-send-email-quic_mpubbise@quicinc.com>
MIME-Version: 1.0
Content-Type: text/plain
Precedence: bulk

Currently in the case of WCN6750, only one TCL ring is
enabled for TX, all TX activity happens only on one ring,
this is limiting the TX throughput in 160Mhz case, enabling
mutliple TCL rings on WCN6750 has shown an improvement of
nearly 300 Mbps in the case of TCP TX, therefore add the
support of multi TX ring for WCN6750.

Tested-on: WCN6750 hw1.0 AHB WLAN.MSL.1.0.1-00573-QCAMSLSWPLZ-1
