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?

ping6 is failing as it should. Can you send a patch to change the
expected rc from 2 to 1?
