Manual tests modifying metrics confirm that GetAdaptersAddresses() sorts the list using the lower of ipv4 and ipv6 metrics, low to high.
The order in which NsiAllocateAndGetTable(NSI_NDIS_IFINFO_TABLE) returns adapters is not affected by route metric.

Manual tests modifying metrics confirm that GetAdaptersAddresses() sorts the list using the lower of ipv4 and ipv6 metrics, low to high.

Hi,
It looks like your patch introduced the new failures shown below. Please investigate and fix them before resubmitting your patch. If they are not new, fixing them anyway would help a lot. Otherwise please ask for the known failures list to be updated.
The tests also ran into some preexisting test failures. If you know how to fix them that would be helpful. See the TestBot job for the details:
The full results can be found at: https://testbot.winehq.org/JobDetails.pl?Key=149724
