5.15 and kernel 6.1. (those kernels are longterm) They need this fix to achieve the performance target.
Why can't they be upgraded to get that performance target, and all the other goodness that those kernels have? We don't normally backport new features, right?
I think this should be considered as a fix, not a new feature.
MANA is designed to be 200GB full duplex at the start. Due to lack of hardware testing capability at early stage of the project, we could only test 100GB for the Linux driver. When hardware is fully capable of reaching designed spec, this bug in the Linux driver shows up.
That part we understand.
If I were you I'd try to convince Greg and Paolo that the change is small and significant for user experience. And answer Greg's question why upgrading the kernel past 6.1 is a challenge in your environment.
