| Subject: [PATCH 005/199] mtk: mt76: mt7996: adjust Beamformee SS capability |
| |
| This commit includes two changes to adjust beamformee ss capability. |
| First, configure the beamformee ss capability for mt7992 chipsets. |
| Second, no matter how many antenna numbers is set, always set the |
| maximum capability of Beamformee SS that chipsets support. |
