            Bug ID: 528
           Summary: ixgbe: PTP not working when ixgbe_xmit_pkts_vec is
                    used
           Product: DPDK
           Version: 20.05
          Hardware: All
                OS: All
            Status: UNCONFIRMED
          Severity: normal
          Priority: Normal
         Component: ethdev
          Assignee: dev at dpdk.org
          Reporter: pawelwod at gmail.com
  Target Milestone: ---

Looks like ixgbe_xmit_pkts_vec is ignoring mbuf ol_flags. When setting any
offloads flag (eg DEV_TX_OFFLOAD_TCP_CKSUM) forces ixgbe_xmit_pkts to be used
and PTP timestamping of transmited packet is working again.
