Intel 810 NIC hashing issue
I'm currently working on a proof of concept for a 100G capable Gatekeeper instance. It has a quartet of these Intel 810 based NICs installed. I've managed to work through a number of hangups, most notably with the ddp firmware, but seem to be getting stuck on this particular hashing related issue. See copypasta from the logs. Let me know if you need more info.

This must add 100g PMD driver to load rss. Currently, the project does not add the PMD driver of intel 810. Currently, the project supports PMD of intel 710x 40g.
If you need to add, you can provide the hardware environment to the project manager, who can help add the PMD driver to load the rss of intel 810.
An update on the Intel 810 NIC.
In order to make this NIC work with Gatekeeper/DPDK, one has to update the package file of the NIC. More information on this is available here. All tests we've done are with package v1.3.40.0, which is currently the latest version. The zip file of the package includes a Technology Guide PDF file with more information on the NIC. The latest version of this PDF is Revision 3.0, released in February 2023.
Due to a bug in DPDK's ICE driver, one must use the branch v1.2.0-dev of Gatekeeper. Gatekeeper v1.2-dev boots and works with IPv4, but not with IPv6 due to another bug still being investigated. One can either ignore IPv6, or disable it by removing the IPv6 addresses of variables front_ips and back_ips in lua/net.lua. Although IPv4 seems to work fine, more tests are needed to homologate the NIC with this setup.
Gatekeeper v1.2-dev works. However, it's under development, so one should not assume it is production ready.
