How to enable rx-fcs parameter on XL710-QDA2 Adapter?

[JLee157]

Hello Team,

I’m writing to make an inquiry about XL710-QDA2 (Dual 40GbE Port NIC).

My customer raised a question on rx-fcs parameters in NIC card (XL710-QDA2).

Customer is attempting to receive corrupted Ethernet frames by using rx-fcs & rx-all in ethtool.

The ultimate goal of this is to capture some errors frames.

By looking at the current configuration of the rx-fcs parameters in that NIC card,

It doesn’t seem to support this operation, which is fixed as OFF at firmware level. 

rx-fcs: off [fixed]

rx-all: off [fixed]

1.

Is there a way of enabling rx-fcs on Intel XL710-QDA2 (Dual 40GbE Port NIC)?

Since it looks to be hardware fixed, Is there any alternative way of this parameter configurable?

2.

If no way exists, then what other product do you recommend for this? (40Gbe dual )

It seems to be depending on NIC card.

some NIC allows the parameter configurable. but some doesnt.

Thanks always for your support

Regards,

Jae

Hello Jlee157, Thank you for posting in Intel Ethernet Communities. Please confirm if this is a retail version of the Intel XL710 QDA2 Ethernet Adapter or an OEM. Please provide an "ethtool -i <interface> output so we can see the drivers and firmware. We will use this information to further check on a solution. Let us know if you have any other questions.

My apology for late response.

still awaiting the output of ehtool -i

The inquiry was about OEM one of  Intel XL710 QDA2 Ethernet Adapter

However I guess retail one is also same - rx-fcs disabled [Fixed]

2 questions

1. curious If this is fixed at chipset level or Firmware level or both.
2. If Intel has 40GbE NIC to make this parameter user configurable, I would suggest to my customer

Sorry again for late reply.

Thanks,

Jae

Hello Jlee157, Thank you for waiting for our update. Please try to do the following commands and let us know of the results. ethtool -K eth0 rx-fcs on ethtool -K eth0 rx-all on If you have any other questions, please do not hesitate to ask.

Thanks Crisselle,

As seen below, It seems not possible to enable the offload If "fixed"

# ethtool -K eno1 rx-fcs on

Could not change any device features

# ethtool -K eno1 rx-all on

Could not change any device features

I assume that the Intel NIC does not support HW FCS at NIC's chip level (not FW level), which means there is no way of FCS possible?

What I'd like to know is

1.If this "Fixed" is at chip level fixed ?

2.Any suggestion for further debugging regarding bad frame (CRC error)?

Thanks again

Jae

Hi Crisselle,

Thanks for your follow-up

no chance to update ethtool version, However the driver is latest one.

Regardless of the version of ethtool & driver, I assume that it is h/w fixed at Chip level or FW level.

The customer seems to be figuring it out via a different way. so we no longer need to go further .

Many thanks Crisselle again for your support and advice

Cheers,

Jae
