            Bug ID: 888
           Summary: cannot close memif port
           Product: DPDK
           Version: 21.11
          Hardware: x86
                OS: Linux
            Status: UNCONFIRMED

code to reproduce bug

I'm trying out DPDK 21.11-rc3 and noticed a regression.

If a port using net_memif driver has been started, it is not possible to cl=
ose
the port.
This is because the rte_eth_dev_close function has a check that the port mu=
st
be stopped, but net_memif driver does not support dev_ops->dev_stop operati=
on.
Consequently, it becomes impossible to stop and close the memif port.
