            Bug ID: 615
           Summary: testpmd gets stuck when deleting an FDIR flow
           Product: DPDK
           Version: 18.11
          Hardware: All
                OS: All
            Status: UNCONFIRMED
          Severity: normal
          Priority: Normal
         Component: ethdev
          Assignee: dev@dpdk.org
          Reporter: alialnu@nvidia.com
  Target Milestone: ---

When deleting a specific FDIR rule (see the last rule below), testpmd will get
stuck.

To reproduce:

- Run testpmd:
testpmd -n 4  -w 0000:00:05.0 -w 0000:00:06.0 -- -i  --rxq=2 --txq=2
--pkt-filter-mode perfect

- Run the following commands in testpmd. The last one will cause testpmd to get
stuck, but I wasn't able to get a trace:

This also reproduces in newer releases that still have legacy FDIR filter type
support.
