Description
Hi Team,
Issue: Clients getting 504 from ALB in a cluster with mixed worker nodes when the selected target is window.
Fix: Manually fixing the MTU in worker node(window) as per (https://docs.aws.amazon.com/AWSEC2/latest/WindowsGuide/network_mtu.html#set-mtu-windows-ena-driver) to Jumbo frames fixes the issue.
Request: Remove the need of manual intervention.

Research direction
No repository files or tests are identified. Start by reading the linked AWS EC2 Windows MTU guidance and investigate how EKS configures MTU on Windows worker nodes in mixed clusters. Done means jumbo-frame MTU is configured without manual intervention and the reported 504s no longer occur when ALB selects a Windows target.
