This reverts commit 078fe45552.
Reason for revert: This change introduced a bug and it completely changed the functionality of WiFi data stall detection, e.g., high Tx link speed can easily trigger data stall. We would like to roll back them to restore the normal functionality of Wifi data stall detection.
