AT_BANNER([multipath link selection])

# The test-multipath program prints a lot of output on stdout, but each of the
# tests below ignores it because it will vary a bit depending on endianness and
# floating point precision.  test-multipath will output an error message on
# stderr and return with exit code 1 if anything really goes wrong.  In each
# case, we list the (approximate) expected output in a comment to aid debugging
# if the test does fail.
