the following e2e test is permanent failing in AWS edge zones: "[sig-network][Feature:tap] should create a pod with a tap interface" affecting CI jobs, specially for edge zones[0].

This is also observed failure in partner ecosystem while validating openshift clusters on platform type External[1].

The common setup is both environments have the first worker node in the list with NoSchedule taints, and the test is ignoring it, never being scheduled in the hard coded[1] worker node.

    4.15+

    Always in AWS edge zone installations - or any cluster with the first worker node in the list with NoSchedule taints.

    1. install a cluster on AWS
    2. apply a NoSchedule taint to the first worker node in the list
    3. run the e2e test "[sig-network][Feature:tap] should create a pod with a tap interface [apigroup:k8s.cni.cncf.io] [Suite:openshift/conformance/parallel]"

The job will not be scheduled:
                lastTransitionTime: "2025-04-06T01:47:26Z"
                message: '0/8 nodes are available: 2 node(s) had untolerated taint {node-role.kubernetes.io/edge:

    The test selects nodes which is able to be scheduled, instead the first in the list.
