hi,

  man ip, the output about exit value is like following.
  "Exit status is 0 if command was successful, and 1 if there is a syntax error.  If an error was reported by the kernel exit status is 2."
  Did the following COMMAND have syntax error? If not, should I still change the expected rc from 2 to 1?

strace of ping6 shows it is failing with '1'.

As for 'ip', it returns the exit code of the command run. iproute2 code,
lib/exec.c, cmd_exec().
