Fix consistent hash based on source IP for TCP proxy #38438

howardjohn · 2022-04-18T22:28:05Z

Fixes test flakes like
https://prow.istio.io/view/gs/istio-prow/logs/integ-ipv6_istio_postsubmit/1514637916112949248

We recently added TCP sourceIP consistent hash. Even more recently, this
test started to fail often. I believe this is due to a change to apply
YAML in parallel, exposing this bug.

The root cause is that we do not push LDS for DR changes, but the config
impacts LDS.

Please provide a description of this PR:

🤔 🐛 You appear to be fixing a bug in Go code, yet your PR doesn't include updates to any test files. Did you forget to add a test?

Courtesy of your friendly test nag.

This is a bug fix, should be backported
