mac80211: add unified BSS configuration
This patch (based on Ron Rindjunsky's) creates a framework for a unified way to pass BSS configuration to drivers that require the information, e.g. for implementing power save mode. This patch introduces new ieee80211_bss_conf structure that is passed to the driver via the new bss_info_changed() callback when the BSS configuration changes. This new BSS configuration infrastructure adds the following new features: * drivers are notified of their association AID * drivers are notified of association status and replaces the erp_ie_changed() callback. The patch also does the relevant driver updates for the latter change.
