Ping check in auto-init mode

If the system is booted using the Auto-init mode procedure, the runtime image performs a ping check to make sure that the system has IP connectivity. The runtime image, after loading the configurations from the configuration file, tries three times to ping the IP address specified in the ping-address parameter in the BOF, at a 2, 8, and 16 minute interval. If the ping check does not succeed, the system is rebooted with the BOF reset after 1 minute and the boot process is repeated. If the address in the BOF is zero or the ping address is not specified, the ping check is not performed.
