            Bug ID: 1640
           Summary: Ethertype filter could receive other packets
                    (non-assigned) in Niantic
           Product: DPDK
           Version: unspecified
          Hardware: All
                OS: All
            Status: UNCONFIRMED
          Severity: normal
          Priority: Normal
         Component: ethdev
          Assignee: dev@dpdk.org
          Reporter: nandinipersad361@gmail.com
  Target Milestone: ---

On Intel® Ethernet Controller 82599EB When Ethertype filter (priority enable)
was set, unmatched packets also could be received on the assigned queue, such
as ARP packets without 802.1q tags or with the user priority not equal to set
value. Launch the testpmd by disabling RSS and with multiply queues, then add
the ethertype filter like the following and then start forwarding:

add_ethertype_filter 0 ethertype 0x0806 priority enable 3 queue 2 index 1
When sending ARP packets without 802.1q tag and with user priority as non-3 by
tester, all the ARP packets can be received on the assigned queue.

Implication:
The user priority comparing in Ethertype filter cannot work probably. It is a
NIC’s issue due to the following: “In fact, ETQF.UP is not functional, and the
information will be added in errata of 82599 and X540.”

Resolution/Workaround:
None

Affected Environment/Platform:
All.

Driver/Module:
Poll Mode Driver (PMD).
