If\nnfp_net_fs_add_hw() fails the old entry stays on nn->fs.list - only the\nsuccess path reaches list_replace() - so the list is one longer than\nnn->fs.count, and it advertises a rule whose hardware entry has already\nbeen torn down.\n\nnn->fs.count is what ETHTOOL_GRXCLSRLCNT reports, so userspace then sizes\nits buffer one entry short of what the GRXCLSRLALL walk wants to write.\nThat used to overwrite one u32 past the allocation; since the walk is\nbounded it is a permanent -EMSGSIZE instead, as nothing ever resyncs the\ncounter."
