Sean WangandFelix Fietkau 82de5987af mt76: mt7921: fix up the monitor mode
Properly set up the monitor mode the firmware can support to fix up
RTS/CTS and beacon frames cannot be captured and forwarded to the host.

Felix Fietkau 64c74dc93f mt76: fix dfs state issue with 160 MHz channels
When operating on a mix of DFS and non-DFS channels, the driver only checks
the CAC status of the control channel. This causes beacons/tx to fail if the
control channel is on a non-DFS channel.
Fix this by calling cfg80211_reg_can_beacon to determine the DFS status of
all affected channels

firmware, so we apply CE command MCU_CE_CMD_SET_EDCA_PARAMS instead which
is supported even in the oldest firmware to properly set up EDCA parameters
for each AC.

Fix the false positive suspend error that may occur on mt7921s
with enlarging mcu timeout value.

The reason why we have to enlarge mcu timeout from HZ / 3 to HZ is
we should consider the additional overhead caused by running
concurrently with btmtksdio (a MT7921 bluetooth SDIO driver) that
would compete for the same SDIO bus in process context to complete
the suspend procedure.

Ryder LeeandFelix Fietkau 12bf28feba mt76: fix iv and CCMP header insertion
The iv from RXD is only for TKIP_RSC/CCMP_PN/GCMP_PN, and it needs a
check for CCMP header insertion. Move mt76_cipher_type to mt76.h to
reduce duplicated code.

Sean WangandFelix Fietkau 1b97dd1762 mt76: mt7921: fix sta_state incorrect implementation
When .sta_state is implemented, mac80211 assumes that the station entry is
usable after the NOTEXIST->NONE transition.

So we should create the sta entry as early as possible in order that
mac80211 pass assoc/auth frames to mt76 with the newly created sta entry,
and add .sta_assoc to mt76 core to refresh the sta entry again when sta is
being associated.

Sean WangandFelix Fietkau ddb3011272 mt76: mt7921: fix reset under the deep sleep is enabled
To fix possibly the race to access register between the WiFi reset
and the other context that is caused by explicitly cancelling ps_work
and wake_work to break PM_STATE consistency.

Deep sleep would cause the hardware into the inactive state,
so we forcely put device drv_own state before we start to reset.

The patch also ignore the reset request when the procedure is in
progress to avoid the consecutive WiFi resets.
