Sorry, wanted to write more about it last week but forgot about it. If I
basically filter out the upper 32 bit in mvm->radio_stats.on_time_rf then it
didn't look that bad on a AX210. It seems like the upper bits is sometimes
0x00000001 for unknown reasons. Like it would be some kind of flag which
should indicate some kind of change/event. So maybe the firmware team could
check what this means.
It is not really urgent - I just got interested in the problem :)
Thanks,
Sven
