            Bug ID: 932
           Summary: tap stop fails because of 'tap_lsc_intr_handle_set()'
                    failure
           Product: DPDK
           Version: 20.11
          Hardware: All
                OS: All
            Status: UNCONFIRMED
          Severity: normal
          Priority: Normal
         Component: ethdev
          Assignee: dev@dpdk.org
          Reporter: ferruh.yigit@intel.com
  Target Milestone: ---

Reproduced with testpmd with following command flow:

./build/app/dpdk-testpmd --vdev net_tap0 --vdev net_tap1 --vdev net_tap2 -- -i

> start tx_first
> stop
> quit

Log:
Stopping port 2...
Stopping ports...
tap_lsc_intr_handle_set(): intr callback unregister failed: -2
free(): invalid pointer
Aborted (core dumped)


Quick debug shows that in 'pmd->intr_handle->fd' is '0' may be reason of the
error.
