            Bug ID: 320
           Summary: mlx4: info get fails in secondary process
           Product: DPDK
           Version: 19.08
          Hardware: All
                OS: All
            Status: UNCONFIRMED
          Severity: normal
          Priority: Normal
         Component: other
          Assignee: dev@dpdk.org
          Reporter: stephen@networkplumber.org
  Target Milestone: ---

Attempts to do dev_info_get in secondary process fail because the driver handle
to infiniband (priv->ctx) is not valid in secondary process. This leads to:

#0  0x00007ffff5d06ab4 in _IO_vfprintf_internal (s=s@entry=0x7fffffffe3c0,
