On some combination of plink_timeout and HZ, the STA expiration timer will be unexpectedly truncated to u32. Maybe there is a question "Who sets such a large number to plink_timeout ?". At least wpa_supplicant will set 0xffffffff to plink_timeout to disable this timer because wpa_supplicant has it's own expiration mechanism.
