From: Baochen Qiang Date: Wed, 20 Oct 2021 08:59:06 +0000 (+0300) Subject: ath11k: change return buffer manager for QCA6390 X-Git-Tag: v6.1-rc5~2306^2~250^2~33^2~75 X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=734223d78428de3c7c7d7bc04daf258085780d90;p=platform%2Fkernel%2Flinux-starfive.git ath11k: change return buffer manager for QCA6390 QCA6390 firmware uses HAL_RX_BUF_RBM_SW1_BM, not HAL_RX_BUF_RBM_SW3_BM. This is needed to fix a case where an A-MSDU has an unexpected LLC/SNAP header in the first subframe (CVE-2020-24588).
