br2684ctl should be keyworded for the following additional arches, like in Debian: ~alpha ~amd64 ~arm ~hppa ~ia64 ~mips ~sparc It will be used by the speedtouch-3 ebuild.
Marked invalid, since the new ebuild "speedtouch-usb" (or whatever it ends up being named) in bug #110665 will only support USB, not Ethernet. So, br2684ctl will not be required after all.
