FS#764 - MT7621: Any traffic shaping results in crashes/stack traces

----------
After 3 days of testing I can tell that the kernel warning is not presenting itself anymore. I did not used SQM or QoS at all, but I tested the SoC under heavy load for hours and nothing happened: no hardlocks, no crash, no kernel errors/warnings, no restarts. Everything looks fine. Previously it took about 5-10 minutes to present the RCU error under heavy load.

I agree that this patch could be merged to trunk, would be a lot easier for us to further test it.
