            Bug ID: 1331
           Summary: net/ice: driver logs an error level message about QinQ
                    support
           Product: DPDK
           Version: 23.07
          Hardware: All
                OS: All
            Status: UNCONFIRMED
          Severity: major
          Priority: Normal
         Component: other
          Assignee: dev@dpdk.org
          Reporter: david.marchand@redhat.com
  Target Milestone: ---

This has been noticed with OVS which refuses any error log level in basic
sanity checks.

This can be easily reproduced with a E810 nic and "default" ddp files.
On a RHEL8 for example, with:

# find /lib/firmware/intel/ice/ddp* ! -type d -exec ls -l {} \;

This error log makes no sense: no QinQ support has been requested.
