We use the deprecated do_gettimeofday() function to read the current time when resetting the statistics in both bfa_port and bfa_svc. This works fine because overflow is handled correctly, but we want to get rid of do_gettimeofday() and using a non-monotonic time suffers from concurrent settimeofday calls and other problems. This uses the ktime_get_seconds() function instead, which does what we need here.
