From 452a6d22615bb8262a932b362f41fc5d89f03293 Mon Sep 17 00:00:00 2001 From: Will Hawkins Date: Tue, 19 Jun 2012 17:59:13 -0400 Subject: [PATCH] mac80211: send auth in IBSS only if userspace isn't handling it Check the auth frame registration count before sending "open system" authentication messages when a new station registers on a particular IBSS network. This stops us from sending out multiple authentication messages with different authentication algorithms.
