From 99d8ed164a9635e5423bd17cc33e934339d41a43 Mon Sep 17 00:00:00 2001 From: Howard Hsu Date: Tue, 14 Jan 2025 18:10:19 +0800 Subject: [PATCH] wifi: mt76: mt7996: fix the capability of reception of EHT MU PPDU This commit includes two changes. First, enable "EHT MU PPDU With 4x EHT-LTF And 0.8us GI" in EHT Phy capabilities element since hardware can support. Second, fix the value of "Maximum number of supported EHT LTFs" in the same element, where the previous setting of 3 in Bit 3-4 was incorrect.
