Hi @zs-ko. Thanks for your PR.

I'm waiting for a kubernetes-sigs member to verify that this patch is reasonable to test. If it is, they should reply with /ok-to-test on its own line. Until that is done, I will not automatically test new commits in this PR, but the usual testing commands by org members will still work. Regular contributors should join the org to skip this step.

Once the patch is verified, the new status will be reflected by the ok-to-test label.

I understand the commands that are listed here.

Instructions for interacting with me using PR comments are available here. If you have questions or suggestions related to my behavior, please file an issue against the kubernetes/test-infra repository.

That's unusual to see a match where TLS and TCP should be the same.
I understand the use case, but I'm unsure if this is the right way to fix it.
@abursavich As the original author of this source, would you please take a look ?

i agree the comment is wrong. It should state that the reason for setting TLS to TCP is to equal these two as to pass true and not cause multiple returns.

The function are basicly doing the same thing with HTTP <-> HTTPS but then in both directions.
