When a specific native VLAN is configured for a port in virtual-wire, the incoming packets still arrive with VLAN ID 4094, while the Virtual Server expects traffic with the configured VLAN ID.
When enabling/disabling virtual-wire mode on a port with a configured native VLAN, the port default VLAN was being set with values (4094 for vwire enable, 4095 for vwire disable), ignoring any existing native VLAN configuration.
Configuring a specific native vlan on a port and then configuring it in virtual-wire.
Once the virtual-wire is configured on the port, if the remove and re-add the native vlans to the interfaces, the hardware should get programmed correctly.
Added a fix such that ensure native VLAN configuration is respected and preserved throughout the virtual-wire lifecycle.
