Sasha,
This requires the whole series from which it came:
https://lore.kernel.org/netdev/20240409073016.367771-1-ericwouds@xxxxxxxxx/
It was merged in
https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/?id=c31bd5b6ff6f70f016e66c0617e0b91fd7aafca4
I don't think this can be easily applied to older kernels, the series
has some dependencies.
