Research direction

Start by reproducing the WSL2 configuration check shown in /proc/config.gz while running Kubernetes with kube-proxy and IPVS. Investigate how WSL kernel configuration is maintained and verify that CONFIG_NF_TABLES_BRIDGE and CONFIG_BRIDGE_NF_EBTABLES are enabled; done means the bridge-support-on-wsl2 workaround is no longer needed.
