I'm using dpdk in google cloud, but I don't know a good way to know which dpdk port corresponds to a network interface on the GCP side for instances with multiple interfaces.

The problem is that GCP doesn't provide API to get MAC address of the interface, so Mac matching is impossible. The next thing is matching IP, but for that, I need to handle the IP assignment(DHCP), and it is not something I want to implement.

Any recommendations?
