Shayne ChenandFelix Fietkau f44685f2fa mt76: mt7915: fix return condition in mt7915_tm_reg_backup_restore()
Fix the issue that some registers not configured properly after
restarting testmode.
(e.g. change state from idle to off, and off to idle)

Shayne ChenandFelix Fietkau e576ddb76d mt76: mt7915: switch proper tx arbiter mode in testmode
Switch proper tx arbiter mode during testmode tx to prevent from
entering the flow of normal tx in FW.
Also, testmode SU and MU tx need to use different arbiter mode.

Shayne ChenandFelix Fietkau fd5b612f9a mt76: mt7915: fix rx fcs error count in testmode
FCS error packets are filtered by default and won't be reported to
driver, so that RX fcs error and PER in testmode always show zero.
Fix this issue by reading fcs error count from hw counter.

We did't fix this issue by disabling fcs error rx filter since it may
let HW suffer some SER errors.

Arnd BergmannandFelix Fietkau 7e1eff6762 mt76: mt7915: fix unused 'mode' variable
clang points out a possible corner case in the mt7915_tm_set_tx_cont()
function if called with invalid arguments:

drivers/net/wireless/mediatek/mt76/mt7915/testmode.c:593:2: warning: variable 'mode' is used uninitialized whenever switch default is taken [-Wsometimes-uninitialized]
        default:

Change it to return an error instead of continuing with invalid data
here.

This is used for specifically configuring TX path, such as different

If spe_idx is not set, TX path depends on tx_antenna_mask; otherwise,
both spe_idx and tx_antenna_mask are referenced to decide TX path.
