   This issue is found on Ubuntu 22.04: the network interface for antrea-gw0
   is different from the one we used in OpenFlow rules.
   
   The reason is systemd-udev has modified the interface's MAC after it watches
   a new one is created. So if Antrea Agent reads interface's information before
   systemd-udev's modification, Antrea Agent would uses an incorrect value to
   install OpenFlow rules.
   
   To resolve the issue,
     1. Agent generates a static MAC for antrea-gw0 or the interface used by Pod
     2. Agent uses the generated MAC to create OVS internal port or veth pair
   
   To implement the logic, some code is copied from containernetworking/plugins/ip/link_linux
   latest versions to path thirdparty, this is to avoid unexpected issues introduced
   when bumping up the dependent libraries.
