mac80211: add supported rates change notification in IBSS
In IBSS it is possible that the supported rates set for a station changes over time (e.g. it gets first initialised as an empty set because of no available information about rates and updated later). In this case the driver has to be notified about the change in order to update its internal table accordingly (if needed). This behaviour is needed by all those drivers that handle rc internally but leave stations management to mac80211 Reported-by: Gui Iribarren <gui@altermundi.net> Signed-off-by: Antonio Quartulli <ordex@autistici.org> [Johannes - add docs, validate IBSS mode only, fix compilation] Signed-off-by: Johannes Berg <johannes.berg@intel.com>
