Subject: [PATCH 2/7] ath10k: change max RX bundle size from 8 to 32 for sdio
Date: Tue, 20 Aug 2019 19:55:03 +0800 [thread overview]
Message-ID: <1566302108-18219-3-git-send-email-wgong@codeaurora.org> (raw)
In-Reply-To: <1566302108-18219-1-git-send-email-wgong@codeaurora.org>
The max bundle size support by firmware is 32, change it from 8 to 32
will help performance. This results in significant performance
improvement on RX path.
Tested with QCA6174 SDIO with firmware
WLAN.RMH.4.4.1-00007-QCARMSWP-1.
