These tests generate various IPv6 flows, encapsulate them in GRE packets and check that the encapsulated packets are distributed between the available nexthops according to the configured weights. Unlike the corresponding IPv4 tests, these tests sometimes fail in the netdev CI because of large discrepancies between the expected and measured ratios [1]. This can be explained by the fact that the IPv4 tests generate about 3,600 different flows whereas the IPv6 tests only generate about 784 different flows (potentially by mistake). Fix by aligning the IPv6 tests to the IPv4 ones and increase the number of generated flows.
