Some nits on the docs.

Regarding the UX, I agree with Tom: do we really need this requirement on the first item of the list being in egressGateway as well?

Not really. I removed that requirement following Tom's guidance.

Integration tests: The failing test is unrelated (github.com/cilium/cilium/pkg/fswatcher). I reran this test locally (privileged and unprivileged) and it worked perfectly. Maybe a flake?

yeah that ones a known flake

Thanks! A couple of comments inline for my codeowners.

Since the boolean v6needed is determined from the CEGP destinationCIDRs
field, we can move it to the PolicyConfig object rather than the
PolicyGatewayConfig.

This change will be very useful for the multigateway Egress Policy
since we plan to have multiple policyGatewayConfig objects per
PolicyConfig. This change will safe from storing the exact same boolean
value in all policyGatewayConfig objects.

This change adds support for parsing the multiple gateways
from a multigateway CEGP and storing them in a PolicyConfig object.

This change doesn't modify how the BPF tables are written.

As discussed in the design the assingment follows a round-robin
algorithm. To create repeatable and stable assignments the lists of
gaterways and endpoints are ordered before the rounds robin-assignment.

To run this test manually please set the kind cluster using the egressgw
preset:
- make kind-egressgw
- make kind-image
- make kind-egressgw-install-cilium

And run it in unsafe mode.

The Cilium E2E Upgrade test failed because Pod test-conn-disrupt-client-5556646476-lzgrb flow was interrupted (restart count does not match 0 != 1). I dug through the logs and found that the pod restarted. I couldn't find any other reference through the logs that will correlate to the changes in this PR. I also don't remember this failure being in the previous test failures we've seen in this CL.

Maybe it's a flake caused by a pod randomly restarting? If so, can someone rerun the tests?

Heads up that these changes were broken on arrival. Evidently we don't have CI coverage for this file, otherwise we would have noticed this earlier. But also in this case the developer didn't test this file and the reviewers didn't test this file, so we merged it in a broken state. This was fixed in #40112.

cc @cilium/egress-gateway as reviewers should we be doing anything differently to avoid introducing breakage like this into the tree?

I recommend we introduce automatic testing for the examples. Maybe with a separate Github flow?

By the way, just mentioning that this file already had a bug in it. When I added the new field I replicated the field above, duplicating the existing bug.

I agree automated testing of example YAML files would be better than expect reviewers catch every indentation and whatnot issues.

Yeah improving the automated testing seems reasonable. In this case, having a short test to load the YAML using the Cilium libraries to verify that it matches the right syntax would have helped; it doesn't have to be an end-to-end test.

By the way, just mentioning that this file already had a bug in it. When I added the new field I replicated the field above, duplicating the existing bug.

If you know about a bug, I would encourage you to submit a fix for it.

In this case the bug I was referring to is introduced by this specific change, because EgressGateways is defined as []EgressGateway and EgressGateway does not have a egressGateway field inside of it.
