ath5k: Add 802.11j 4.9GHz channels to allowed channels
Add the 802.11j (20MHz channel width) channels to the allowed channels. This still does not enable 802.11j in ath5k since these frequencies are out of the configured range. A later patch will deal with that. Signed-off-by: Bruno Randolf <br1@einfach.org> Acked-by: Bob Copeland <me@bobcopeland.com> Acked-by: Nick Kossifidis <mickflemm@gmail.com> Signed-off-by: John W.
