E810-C does not forward lldp

StefanMajer

Hi, 

I have a Server running ubuntu-20.04 with two E810-C cards connected to two Edgecore AS7732-12. This is the first server with the 810 series card, the farm we have is equipped with xxv710 25G models. 

We run a small lldpd https://github.com/metal-stack/go-lldpd on all machines to send custom TLVs via lldp. This is required for our bare metal provisioning.

This works fine for XXV710 and X550 type ethernet cards, but not with the e800 family.

The only lldpd which is able to send lldp frames is lldpad, but this daemon does not allow to send SystemName/SystemDescription with own content.

All other lldpd implementation does not work. We are pretty sure this is due the fact that this card has DCB as a hard requirement. 

Any hints howto make vanilla lldp daemons work here ?

Greetings

Stefan Majer

Trying to update the firmware with the most recent (2.42) version leads to:

with

./nvmupdate64e -a .

and with the next older one (2.32) gives me after ~20mins:

Hello StefanMajer,


Thank you for posting in Intel Ethernet Communities. 


Please provide the following information that would help in checking your request.

1. What is the exact Operating System used?

2. Where was the driver version: 0.8.2-k and firmware 2.30 0x80005d1e 1.2877.0 downloaded from? 

3. Have you tried using the Intel ice driver that can be downloaded from link below? 

Intel® Network Adapter Driver for E810 Series Devices under Linux*

https://downloadcenter.intel.com/download/29746/Intel-Network-Adapter-Driver-for-E810-Series-Devices...

4. Will you be able to provide photos of the adapter focusing on the white sticker markings? This will help us identify if you are using an Original Equipment Manufacturer (OEM) or retail version of Intel Ethernet Adapter. We will send an email for you to send the photos. Please be reminded not to post the photos on this thread to avoid exposing confidential information.


We hope to hear from you soon. 


Should there be no response from you, I’ll make sure to reach out after 3 business days.


Best regards,

Crisselle C.

Operating System:

- ubuntu 20.04 with HWE Kernel

- The ice driver is from the HWE kernel package ubuntu provides and matches the most recent 5.8.x vanilla kernel and the ice driver version included there

- The firmware is unmodified and the card is provided directly from Intel ! 

 

Same behavior with a stock vanilla 5.10.26 kernel and the matching ice driver.

This is a quite serious issue for us because we are going to order hundreds of servers equipped which this type of cards as a update to our existing fleet of servers with XXV710 cards deployed where all LLDPd operations work. 

I also tried some other lldpd implementation like https://github.com/lldpd/lldpd which also works without any issues on the XXV710 but does not work on the e810.

Hello StefanMajer,


I hope this message finds you well!


Our engineer is requesting for the following information. We hope you don't mind sharing this with us. 

1.Adapter's markings. We need the PBA markings for validation. You may refer to the link below on where to find the PBA number. Providing photos of the adapter focusing on the markings (white sticker) found on the physical card will be highly appreciated for us to double check on it. The PBA consists 6-3 digit number located at the last part of the serial number. We will be sending an email for you to attach the photos of the adapter. Please be reminded not to post the photos on this thread to avoid exposing confidential information. If providing the photos is not possible, the PBA number will do. 

Identify Your Intel® Network Adapter Model Using PBA Number

Hello Stefan,


Thank you for the patience on this matter.


We already received an update from our engineers and they found out that you are using driver version 0.8.2-k. In order to update the Firmware, you need to use first the latest Linux driver which is 1.4.11.

https://sourceforge.net/projects/e1000/files/ice%20stable/1.4.11/


Once the driver is updated, update the Firmware to version 2.42

https://downloadcenter.intel.com/download/29738/Non-Volatile-Memory-NVM-Update-Utility-for-Intel-Eth...


In regard to your concern about LLDP and DCB, we have found the readme file that has an entire section detailing LLDP and DCBX in both Firmware and Software mode. Kindly use the recommended driver, update the Firmware and consult the readme.

https://www.kernel.org/doc/html/latest/networking/device_drivers/ethernet/intel/ice.html


In firmware-based mode, firmware intercepts all LLDP traffic and handles DCBX

negotiation transparently for the user. In this mode, the adapter operates in

"willing" DCBX mode, receiving DCB settings from the link partner (typically a

switch). The local user can only query the negotiated DCB configuration. For

information on configuring DCBX parameters on a switch, please consult the

switch manufacturer's documentation.


In software-based mode, LLDP traffic is forwarded to the network stack and user

space, where a software agent can handle it. In this mode, the adapter can

operate in either "willing" or "nonwilling" DCBX mode and DCB configuration can

be both queried and set locally. This mode requires the FW-based LLDP Agent to

be disabled.


Feel free to let us know if you have questions or clarifications.


Awaiting to your reply.


We will follow up after 3 business days in case we don't hear from you.

Hi Support,

thanks for the pointer to the ice kernel driver update, this is not so easy to do if you must install a Distribution which does not have the ability to deploy self deployed kernel drivers. In our case we need to support centos and debian.

But i will check this to be able to at least update the firmware to the latest version.

 

Your explanation regarding the support of "vanilla" lldp, this is wrong. I got from another source the hint that your card actually requires that the LLDP Ethernet frames are sent to a socket which socket priority ist set to at least TC_PRIO_CONTROL (7). Otherwise the ice driver will not forward this Ethernet Frame out of the card itself. I was able to test this and send LLDP packets through your e810 card without any kernel driver or firmware updates.

I also checked the source of lldpad (your lldpd implementation) and other lldpd implementations out there. The only lldpd server implementation is lldpad which actually set the socket priority to TC_PRIO_CONTROL.

 

Please update your documentation in this aspect, because other users out there should not spend 3 weeks or more on this topic as i did.

 

I am also not very pleased with the support i got from this channel tbh. 

 

Greetings

Stefan Majer

Hello Stefan,


Thank you for the patience on this matter. Please see below information for the update from our Engineering team.


Your statement regarding LLDP is accurate for driver versions 1.4.11 and older. This issue (PF LLDP bug) was found and fixed in the upcoming 26.3 release (driver ice-1.5.4).


Issue: The driver was incorrectly flagging egressing packets which causes LLDP packets to be dropped from interfaces. 


Fix: The newer driver adds better checking to determine if the egressing packets are LLDP packets or not.


Release 26.3 should be available in the next couple of weeks. The 26.3 release notes might have a better description text on the issue and fix.


Feel free to let us know if you have additional questions and clarifications.


Best regards,
