According to the firmware usage, OFDM rates should fill out bit 6 - 13 while CCK rates should fill out bit 0 - 3 in legacy field of RA info to make the rate adaption runs propertly. Otherwise, a unicast frame might be picking up the unsupported rate to send out. Fixes: 1c099ab4 ("mt76: mt7921: add MCU support") Reported-by:

Update the proper firmware programming sequence to fix GTK rekey offload failure on WPA mixed mode. In the mt76_connac_mcu_key_iter, gtk_tlv->proto should be only set up on pairwise key and gtk_tlk->group_cipher should be only set up on the group key. Otherwise, those parameters required by firmware would be set incorrectly to cause GTK rekey offload failure on WPA mixed mode and then disconnection follows.

Fix the current driver mgmt frame is not respecting the basic rates field provided by the AP and then unconditionally is using the lowest (1 or 6 Mbps) rate. For example, if the AP only supported basic rate {24, 36, 48, 54} Mbps, mt7921 cannot send mgmt frame with the rate not in the group. So, instead, we pick up the lowest basic rate the AP can support to send. Fixes: e57b7901 ("mt76: add mac80211 driver for MT7915 PCIe-based chipsets") Suggested-by: -

mt7921 is mainly used in NB, CE and IoT application where battery life is much concerned so the patch enabled PCIe ASPM by default to shut off the clocks related PCIe as much as possible when MT7921 is either in suspend state or in runtime pm to lower power consumption.
