Cap max peerings at 63 in accordance with IEEE-2012 8.4.2.100.7. Triggers a beacon regeneration every time the number of peerings changes. Previously this would only happen if the "accepting peerings" bit changed. Signed-off-by: Jacob Minshall <jacob@cozybit.com> Signed-off-by: Johannes Berg <johannes.berg@intel.com>
