Use C language for timingIn user space, you can use the C language function gettimeofday to get the time. The call format is: # Include Int gettimeofday (struct timeval * TV, struct timezone * tz );Int settimeofday (const struct timeval * TV, const

On as4, device bnx2 does not seem to be present and delaying initialization may be reported. The cause of this problem seems to be different, and different situations have different solutions. If this problem occurs after commands such as
