            Bug ID: 1007
           Summary: ixgbe-bound x553 sibling interface broken after app
                    crash
           Product: DPDK
           Version: 20.11
          Hardware: x86
                OS: Linux
            Status: UNCONFIRMED
          Severity: normal
          Priority: Normal
         Component: ethdev
          Assignee: dev@dpdk.org
          Reporter: dmontgomery@juniper.net
  Target Milestone: ---

We have two interfaces on one chipset, one bound to igb_uio for use in a DP=
DK
application, the sibling still owned by linux.  After an application crash,=
 the
device we were *not* using stops receiving packets.

dpdk-devbind.py snippet:

[root@sn9120210013 ~]# dpdk-devbind.py --status

0000:02:00.0 'Ethernet Connection X553 1GbE 15e4' if=3Denp2s0f0 drv=3Dixgbe
unused=3Digb_uio,vfio-pci

Using ethtool on enp2s0f0, we see these counters:

     rx_packets: 1389712
     rx_bytes: 478998162
     rx_pkts_nic: 1398666
     rx_bytes_nic: 485323772

rx_packets and rx_bytes halt, but rx_pkts_nic and rx_bytes_nic continue
incrementing.

Is there any chance there is bleedover to sibling devices inside the PMD co=
de?
