Root Cuase:

 1. GCP instance driver net_virtio didn't support hw_vlan_filter feature

 2. net_virtio dirver has max 2 eth queue to receive packet but we just assign 1 as default setting
Fix:

1. Disable hw_vlan_filter feature when atcp process notice it is running on GCP instance

2. increase net_virtio dirver max eth queue number to 2

Generate customized qcow2 image
upload to GCP
create an instance and bootup
check if there is atcp_veth interface with IP assigned by DHCP
