    Subject[PATCH 5.15 462/917] mt76: connac: fix mt76_connac_gtk_rekey_tlv usage
    Date
    From: Leon Yen <Leon.Yen@mediatek.com>

    [ Upstream commit d741abeafa47a7331cd4fe526e44db4ad3da0f62 ]

    The mistaken structure is introduced since we added the GTK rekey offload
    to mt7663. The patch fixes mt76_connac_gtk_rekey_tlv structure according
    to the MT7663 and MT7921 firmware we have submitted into
    linux-firmware.git.

    Fixes: b47e21e75c80 ("mt76: mt7615: add gtk rekey offload support")
