parse_line

parse_line($string);

This test (and udpgro_fwd.sh, veth.sh) print a description padded with 'printf', then append the status on the same line, e.g.:

#  no GRO                                  ok
# UDP fwd perf                             skip - needed 2 CPUs found 1

Lines that do not match this format are returned unchanged. A skip status is left untouched rather than converted (see net.pm).
