ice(?) memory leak in Proxmox 9

[BlueMatt]

After upgrading to proxmox 9 my hosts that use the ice driver (ie Intel 25G NICs) for the ceph network (with jumbo frames) show a pretty quick memory leak (something like 10GB/day). I assume it was fixed in upstream kernel commit 84bf1ac85af84d354c7a2fdbdc0d4efc8aaec34b, any chance we could get a backport of that?

Known issue that's being addressed currently. You can try an experimental kernel build if you're brave:

https://lore.kernel.org/all/20250825-jk-ice-fix-rx-mem-leak-v2-1-5afbb654aebb@intel.com/ seems like a likely fix for this memory leak, a test kernel is available here and we'd appreciate feedback on whether it fixes your issues:

thanks!

thank you for providing the kernel build with the Intel E810 ICE driver fix. I deployed it on four nodes equipped with E810 NICs. Over the weekend the systems were generally running, but I observed that memory usage on the E810 nodes was not stable. The curve was flatter...
