[PATCH v2 net-next 4/4] selftests: forwarding: Add description to the multipath tests

[dsahern at gmail.com (David Ahern)]

Add a better description to the summary for multipath tests. e.g.,

INFO: Running IPv6 multipath tests
TEST: ECMP                                               [PASS]
INFO: Expected ratio 1.00 Measured ratio 1.02
TEST: Weighted MP 2:1                                    [PASS]
INFO: Expected ratio 2.00 Measured ratio 2.02
TEST: Weighted MP 11:45                                  [PASS]
INFO: Expected ratio 4.09 Measured ratio 4.03
