Neutron MTU Path Discovery Fails to Detect Correct MTU in VXLAN-Production Deployments
Goal: Verify that Neutron's mtu_path_discovery feature can automatically determine the correct MTU for tenant networks that use VXLAN encapsulation in a production environment, ensuring that guest instances do not experience packet fragmentation or TCP hangs. Constraints: The feature's behavior varies across different Linux kernel releases and virtual switch
