            Bug ID: 936
           Summary: DPDK init for i40e pmd fails
           Product: DPDK
           Version: 20.11
          Hardware: x86
                OS: Linux
            Status: UNCONFIRMED
          Severity: major
          Priority: Normal
         Component: ethdev
          Assignee: dev at dpdk.org
          Reporter: girish_potti at affirmednetworks.com
  Target Milestone: ---

The guest is running debian and dpdk 20.11.3  i40evf PMD on VF and Host running
i40e 2.12.6.3 on PF. 
When the guest comes up and initializes it fails with the error.
i40evf_check_api_version(): PF/VF API version mismatch:(0.0)-(1.1)
i40evf_check_api_version(): PF/VF API version mismatch:(0.0)-(1.1)
 i40evf_init_vf(): check_api version failed
 i40evf_init_vf(): check_api version failed

This happens only rarely. 98% of the time init is fine.
