            Bug ID: 57
           Summary: ixgbe crash on detach when no VF is created
           Product: DPDK
           Version: 18.05
          Hardware: All
                OS: Linux
            Status: CONFIRMED
          Severity: normal
          Priority: Normal
         Component: ethdev
          Assignee: [email protected]

Target Milestone: ---

Issue reported by Anatoly Burakov <[email protected]>

Steps to reproduce (with ixgbe port):
./testpmd -- -i

Quoted 3 lines

port stop all
port close all
port detach 0

The reason of the crash is:
(*vfinfo) is a null pointer at that point, -> dereferences it.

The issue is introduced in:
commit cf80ba6e2038a54b6c5ba62ce4200234f5aa3880
