Deren WuandFelix Fietkau 150bb95cb1 wifi: mt76: mt7921: do not support one stream on secondary antenna only
mt7921 support following antenna combiantions only.
* primary + secondary (2x2)
* primary only        (1x1)

Since we cannot work on secondary antenna only, return error if the
antenna bitmap is 0x2 in .set_antenna().

For example:
iw phy0 set antenna 3 3 /* valid */
iw phy0 set antenna 1 1 /* valid */
iw phy0 set antenna 2 2 /* invalid */

Deren WuandFelix Fietkau 282845ce7f wifi: mt76: mt7921: fix wrong command to set STA channel
Should not use AND operator to check vif type NL80211_IFTYPE_MONITOR, and
that will cause we go into sniffer command for both STA and MONITOR
mode. However, the sniffer command would set channel properly (with some
extra options), the STA mode still works even if using the wrong
command.

Fix vif type check to make sure we using the right command to update
channel.

The rx filter, in mt7921 series, may be changed in fw operation. There is
a racing problem if rx filter controlled by both driver and firmware at
the same time. To avoid this issue, let mt7921 driver set rx filter by new
command MCU_CE_CMD_SET_RX_FILTER and allow the firmware controlling it
only.

Sean WangandFelix Fietkau 2575de3aea wifi: mt76: mt7921: introduce chanctx support
The firmware can have the capability to manage the channel context
scheduling on multiple roles running on the device including Station,
AP and P2P GC/GO mode (will be extended based on the future patchset)
to help users sharing the network with others on a single device.

The firmware is able to support the channel chanctx up to 2 interface
simultaneously running on the different channels.

Another thing to be noted is that before the driver is going sent out the
management frames, the driver has to get the privilege from the firmware
to occupy the current channel context until the frame handshake is
completed and then get the privilege back to the firmware.

Sean WangandFelix Fietkau 47b64131e8 mt76: mt7921: don't enable beacon filter when IEEE80211_CONF_CHANGE_MONITOR is set
IEEE80211_CONF_CHANGE_MONITOR would be set every time even when vif runs as
sta mode.

If vif runs as sta mode, the beacon filter would be falsely enabled
earlier than the associated state.

That is not the behavior the firmware expects and also breaks the original
logic of sta mode. Thus, we only limit the operation to set the beacon
filter only for monitor mode when IEEE80211_CONF_CHANGE_MONITOR is set.

If the nic fails to start, it is possible that the

work item is canceled so we do not have use-after-free
crash in case cleanup is called before the work item
is executed.

According to the MT7921S firmware, the cmd MCU_UNI_CMD_HIF_CTRL have to
be last MCU command to execute in suspend handler and all data traffic
have to be stopped before the cmd MCU_UNI_CMD_HIF_CTRL starts as well
in order that mt7921 can successfully fall into the deep sleep mode.

Where we reuse the flag MT76_STATE_SUSPEND and avoid creating
another global flag to stop all of the traffic onto the SDIO bus.
