[PATCH] rt2x00: Reorganize configuration handler
Reorganize configuration handling by creating a extra structure which contains precalculated values based on the mac80211 values which are usefull for all individual drivers. This also fixes the preamble configuration problem, up untill now preamble was never configured since by default the rate->val value was used when changing the mode. Now rate->val will only be used to set the basic rate mask. The preamble configuration will now be done correctly through the erp_ie_changed callback function.
