| Subject: [PATCH 191/223] mtk: 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. |
