| Subject: [PATCH 59/61] mtk: wifi: mt76: mt7996: Do MLD address translation |
| before STA process BMC mgmt. frame |
| |
| In the function ieee80211_prepare_and_rx_handle(), BMC mgmt. frames are |
| not MLD translated since the AAD calculation needs the header being link |
| addressed. However, after the AAD calculation, STA processes the mgmt. |
| frames on an MLD level, and it fails to match the link address in the |
| header with the self MLD address. |
| |
| This commit does MLD address translation again after the AAD calculation |
| and before STA's mgmt. frames processing. |
