I guess it fits the bill of "a real bug that bothers people", what OpenWrt wants is to use their simple userspace to set up class-e addresses and without this patch, this doesn't work for them, and IIUC it could be expected to work. I guess it is an ontological question whether OpenWrt are "fixning" or "stabilizing" or "adding features" by making class-e networks work with good old ifconfig. The maintainer(s) will decide. > Either way, David Miller will need to sign off on this since he manages > net/ -stable patches. I was unaware of different route points for stable patches, but it makes sense. Maybe we should add some kind of tagging entries to MAINTAINERS so it is clear where to route stable material? Right now I guess it is another one of these undocumented rules that one is supposed to pick up by first annoying everyone :D Are there other subsystems that have a second-level maintainer for stable, so I know before annoying someone else?
