f937275364 mt76: mt7915: set VTA bit in tx descriptor
The VTA (Valid for Txd Arrival time) bit should be set in tx descriptor,
which is necessary for WM fw to schedule SPL (station priority list)
normally before generating txcmd.
If it's not set, some unexpected wcids may be involved in SPL.

a1b0bbd484 mt76: use a separate CCMP PN receive counter for management frames
When received frame is decryped by hardware, CCMP PN is checked by
mt76.

When management frame protection (IEEE 802.11w) is used, we must use
a separate counter for tracking received CCMP packet number for the
management frames. The previously used counter was shared with data
frames and that can cause problems in detecting replays incorrectly
for robust management frames.

Add a new counter just for robust management frames to avoid this
issue.

a90f2115c1 mt76: mt7915: add more MIB registers
Add register definitions and read & accumulate them in
the mib polling logic.  Note that some registers should not
be read since firmware is already reading them.  If driver
reads those, they will be cleared-on-read, and so the firmware
stats will be incorrect.

For these 'do-not-read' stats, add them to the registers definition
so that other developers can be aware of these constraints, but do
not actually read them in the driver.

016f204059 mt76: mt7915: add tx mu/su counters to mib
These counters are clear-on-read, so we need to accumulate
them in the update_stats poll logic, and read the accumulated
values instead of directly doing register reads when reporting
to debugfs and ethtool stats.
