When using the -oneline option, this will work just fine: TEST: ipv6: list and flush cached exceptions [ OK ] This also works just fine with a more recent version of iproute2, like 5.4.0. For some reason, two lines are printed for the IPv4 test no matter what version of iproute2 is used. Use the same -oneline parameter there instead of counting the lines twice.
