Maybe just rate limit register reading in the sysfs interface? Something like: we've just updated the stats a second ago, use the old data ... Or as a different idea, schedule a work from the tx status path (the counters can only change if we transmit something), also rate limited ... This could be used for rt2800pci as well then ...
