The loop this patch fixes has been unchanged since 95698ff6177b ("net: fec: using page pool to manage RX buffers") in v6.1, so every stable tree from 6.1.y onwards carries it. I checked 6.12.y in particular: the code there is byte identical to 6.18.y, so the patch applies without any change, and the crash is reachable on the same terms. Please take it into whichever of those trees you consider appropriate, not 6.18.y alone. I only tagged 6.18.y because that is the tree I reproduced and tested it on. Thanks, Mehmet
