<p class="MsoNormal">Hi,<o:p></o:p></p>
<p class="MsoNormal">I have Intel x710-DA4 NIC configured as SR-IOV or PCI-PT.<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">The DPDK 17.11 rte_eth_tx_burst() API says the packet is transmitted successfully, but over time the available mbufs continues to shrink until no mbufs available.<o:p></o:p></p>
<p class="MsoNormal">When I monitor the X710 port output I see the first mbuf transmitted from the X710 port but not the second mbuf.<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">I also made sure the tx.offloads has DEV_TX_OFFLOAD_MULTI_SEGS set if capability bit is set.<o:p></o:p></p>
<p class="MsoNormal">I reviewed the mbuf details (both first and second mbufs) and all looks correct and identical.<o:p></o:p></p>
<p class="MsoNormal">In DPDK 17.11 I see the failure but in DPDK 22.11 I don’t see the failure.<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">Intel x710-DA4 driver/firmware is 1.11.1.31/6.80<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">Does anyone know why this occurs and how to fix it? Is the issue in the Intel i40e driver?<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">Thanks,<o:p></o:p></p>
