I need to know how to make RSS work for SRv6

I am developing on your product Connect5X EN 50GbE.Very good product!

Specifically, we are using XDP to implement SRv6 functionality.

So I have a question. Does this NIC allow RSS to work against SRv6 (i.e.

IPv6 Exthdr)?

https://github.com/torvalds/linux/commit/a795d8db2a6d3c6f80e7002dd6357e6736dad1b6

As far as I could tell, IPIP6 is supported, so I thought it might work.

However, so far I have not been able to use multi-core.

If you do support it, could you please tell me how to use it?

Thank you.

Hello Takeru,

Thank you for posting your inquiry to the Mellanox community.

We will need some further information in order to assist you further:

  1. What is the part number of the HCA in question? This can be obtained via:

lspci -d 15b3: -vv | grep PN

  1. What firmware revision is installed on the HCA?

  2. What OS and kernel version is installed on this system?

  3. Are you using MLNX_OFED, or inbox (upstream OS) drivers?

  4. You mention that you are not able to use multi-core - could you elaborate as to what you mean by that? What steps are you taking in order to configure RSS?

Thank you, and we look forward to hearing from you soon.

Best regards,
