{cfg,nl,mac}80211: set beacon interval and DTIM period on mesh join
Move the default mesh beacon interval and DTIM period to cfg80211 and make them accessible to nl80211. This enables setting both values when joining an MBSS. Previously the DTIM parameter was not set by mac80211 so the driver's default value was used. Signed-off-by: Marco Porsch <marco@cozybit.com> Signed-off-by: Johannes Berg <johannes.berg@intel.com>
