Hi,

I have Intel x710-DA4 NIC configured as SR-IOV or PC= I-PT.

 

The DPDK 17.11 rte_eth_tx_burst() API says the packe= t is transmitted successfully, but over time the available mbufs continues = to shrink until no mbufs available.

When I monitor the X710 port output I see the first = mbuf transmitted from the X710 port but not the second mbuf.

 

 

I also made sure the tx.offloads has DEV_TX_OFFLOAD_= MULTI_SEGS set if capability bit is set.

I reviewed the mbuf details (both first and second m= bufs) and all looks correct and identical.

In DPDK 17.11 I see the failure but in DPDK 22.11 I = don’t see the failure.

 

Intel x710-DA4 driver/firmware is 1.11.1.31/6.80

 

Does anyone know why this occurs and how to fix it?&= nbsp; Is the issue in the Intel i40e driver?

 

Thanks,

Ed
