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.
