PA-VMARM DPDK mode does not recognize attached ENIs when AWS instance type is C6gn
Symptom
• Interface status remained stuck in "ukn/ukn/down((autoneg))" after applying network interface configuration.
• The interface did not have a MAC address after checking the logs.
• Rebooting the instance did not resolve the issue.
• Detaching and reattaching the ENI did not resolve the issue.
**ERROR_LOGS**
• The MAC address does not look to be assigned. interface show all command indicated this.

Environment
**Product_versions**
• PANOS: 11.2
• AWS: C6gn instance type
• PA-VMARM
Cause
C6gn instance was supported earlier. However, due to a known AWS side symptom, we will not support C6gn instance any longer.
Resolution
Please use other instance type.
Additional Information
Changing the packet io type to MMAP could recognize the attached ENIs.
However, due to a known AWS side symptom, we will not support C6gn instance any longer.
