From e39e5b5e7206767a0f1be0e5cb7acbd0db87ae60 Mon Sep 17 00:00:00 2001 From: Jouni Malinen Date: Sun, 30 Sep 2012 19:29:39 +0300 Subject: cfg80211: Allow user space to specify non-IEs to SAE Authentication SAE extends Authentication frames with fields that are not information elements. NL80211_ATTR_IE is not suitable for these, so introduce a new attribute that can be used to specify the fields needed for SAE in station mode.

This is useful for collecting guaranteed fresh scan/survey result (e.g. on resume). For normal scan, flushing only happens on successful completion of a scan; i.e. it does not happen if the scan is aborted. For scheduled scan, previous scan results are flushed everytime when we get new scan results. This feature is enabled by default. Drivers can disable it by unsetting the NL80211_FEATURE_SCAN_FLUSH flag.
