If it is fully loaded with filters then it is possible that it will take more than 200 ms to finish the reset resulting in timeout during pf_reset and PF reset failed, -15 error indication. Increasing the timeout value for PF reset from 200 to 1000 to give PF more time to finish reset if it is loaded with filters.
