Hello All,

I'm trying to run DPDK-PKTGEN in AWS EC2 instances and able to send packets up to 1.5 KB packets.
If we use Jumbo frame packets then we are getting error "requested Tx offloads 0x8000 doesn't match Tx offloads capabilities 0xe".

Setup:
Ubuntu: 16.04
Driver: ENA 2.0.3K
DPDK: 18.11.1
PKTGEN: 3.7.1

Can anyone help me with this issue ? Is anything I'm missing ?

Thanks,
Anand

[KW] Please update to the latest Pktgen 21.02.0 with the latest DPDK version. If you can’t upgrade then please look at the latest version as some work for jumbo frames has been done.

Hi Keith,

I found the root cause for the problem " requested Tx offloads 0x8000 doesn't match Tx offloads capabilities 0xe" in EC2 instances.
The DPDK ENA driver does not have "DEV_TX_OFFLOAD_MULTI_SEGS" TX offload capability in TX offloads capabilities and in Pktgen when Jumbo frame is enabled, the TX-offload adds " DEV_TX_OFFLOAD_MULTI_SEGS".
 
Is "DEV_TX_OFFLOAD_MULTI_SEGS" necessary when the Jumbo frame is enable in the Pktgen or can we first check if the Device supports the offload or not and then add " DEV_TX_OFFLOAD_MULTI_SEGS"?
 
What is the mechanism of "DEV_TX_OFFLOAD_MULTI_SEGS" when enabling Jumbo frames?

Thanks,
Anand

We can try to test for Multi-segs in pktgen in the file app/pktgen-port-cfg.c you can search for MULTI_SEGS and add the test.

                        if (info->dev_info.tx_offload_capa & DEV_TX_OFFLOAD_MULTI_SEGS)
                                conf.txmode.offloads |= DEV_TX_OFFLOAD_MULTI_SEGS;

Hi Keith,

Thanks for the reply.

Can you explain if possible what does "DEV_TX_OFFLOAD_MULTI_SEGS" do if it is used in TX-Offload ? What is the use of this in Jumbo frame scenario?

Thanks,
Anand

The DPDK code states:

#define DEV_TX_OFFLOAD_MULTI_SEGS       0x00008000 /**< Device supports multi segment send. */

That is all I know about this option, maybe someone else can explain how the drivers use this option.
