            Bug ID: 1916
           Summary: Scapy version (arm-grace) fails to add rss hash
                    attribute to tx packets
           Product: DPDK
           Version: unspecified
          Hardware: All
                OS: All
            Status: UNCONFIRMED
          Severity: normal
          Priority: Normal
         Component: DTS
          Assignee: dev@dpdk.org
          Reporter: dmarx@iol.unh.edu
                CC: juraj.linkes@pantheon.tech, probb@iol.unh.edu
  Target Milestone: ---

There is an issue with the Scapy version on arm-grace not generating an rss
hash attribute in Tx packets, which is causing an error in the rss suite:

key_hash_algorithm: ERROR
      reason: Unhandled exception raised: Packet sent by the Traffic Genera=
tor
has no RSS hash attribute.

The logic within the case is handled entirely by Scapy:

# Get packet hash
packet_hash =3D packet.rss_hash
