When USES_RSS is enabled, last_rx becomes zero in first few minutes after sta connection in sta_get_last_rx_stats. This leads to inactive time showing current jiffies in msecs. Station 8c:fd:f0:02:10:dd (on wlan0) inactive time: 4294701656 ms . . connected time: 2 seconds Fix this by avoid overwriting last_rx with percpu_stat's last_rx if it is zero.
