            Bug ID: 54
           Summary: i40e port link status no updated for interrupt mode
           Product: DPDK
           Version: 18.05
          Hardware: All
                OS: All
            Status: CONFIRMED
          Severity: major
          Priority: Normal
         Component: eventdev
          Assignee: dev at dpdk.org
          Reporter: roy.fan.zhang at intel.com
  Target Milestone: ---

The link status of i40e port remains unchanged regardless of
connecting/disconnecting the physical cable.

Starting testpmd with default interrupt mode.

testpmd> show port info all
...
Link status: down
...

Packet generator shows link up but i40e link status change interrupt is not
activated.

If the link is up initially, disconnecting the cable will have no effect on
link status as well.
