stable inclusion from stable-v5.10.94 commit 754b663ea9167d03604898b3a2253ff58ad06a71 bugzilla: https://gitee.com/openeuler/kernel/issues/I531X9 Reference: https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git/commit/?id=754b663ea9167d03604898b3a2253ff58ad06a71 -------------------------------- [ Upstream commit 04be6d33 ] Some AP can possibly try non-standard VHT rate and mac80211 warns and drops packets, and leads low TCP throughput. Rate marked as a VHT rate but data is invalid: MCS: 10, NSS: 2 WARNING: CPU: 1 PID: 7817 at net/mac80211/rx.c:4856 ieee80211_rx_list+0x223/0x2f0 [mac8021 Since commit c27aa56a ("cfg80211: add VHT rate entries for MCS-10 and MCS-11") has added, mac80211 adds this support as well. After this patch, throughput is good and iw can get the bitrate: rx bitrate: 975.1 MBit/s VHT-MCS 10 80MHz short GI VHT-NSS 2 or rx bitrate: 1083.3 MBit/s VHT-MCS 11 80MHz short GI VHT-NSS 2 Buglink: https://bugzilla.suse.com/show_bug.cgi?id=1192891Reported-by: NGoldwyn Rodrigues <rgoldwyn@suse.com> Signed-off-by: NPing-Ke Shih <pkshih@realtek.com> Link: https://lore.kernel.org/r/20220103013623.17052-1-pkshih@realtek.comSigned-off-by: NJohannes Berg <johannes.berg@intel.com> Signed-off-by: NSasha Levin <sashal@kernel.org> Signed-off-by: NZheng Zengkai <zhengzengkai@huawei.com> Acked-by: NXie XiuQi <xiexiuqi@huawei.com>
