In order to later add tracing or verifications to the driver calls mac80211 makes, this patch adds static inline wrappers for all operations. All calls are now written as drv_<op>(local, ...); instead of local->ops-><op>(&local->hw, ...); Where necessary, the wrappers also do existence checking and return default values as appropriate.
