That said, the page pool warnings were probabilistic to begin with. And they were hit in page_pool_unref_netmem(), I think _some_ bug must still be there? IOW mlx5e_page_release_fragmented() is draining more references than the pp page use counter, that's not normal whether some command timeout out or not.
