It's not a sysctl, it is an ioctl against /dev/elan-mmrc.

If you kill watchdogd with a normal "kill", it will disable the timer 
before exiting.  Just what you want.

When the watchdogd starts up, it enables the timer for a 32 second 
interval, and then starts resetting it every 16 seconds.

If you "kill -9" the watchdog daemon (so it can't stop the timer before 
exiting) your net45xx will reset in 15 to 30 seconds.

You won't find this in the 4.9-RELEASE documentation, it's backported from 
5.1.  Check
for more information.
