From fb915d50fddc0d66834030734425bd5e93c67ce1 Mon Sep 17 00:00:00 2001 From: Jouni Malinen Date: Thu, 24 Mar 2016 12:17:46 +0200 Subject: [PATCH] tests: WNM BSS Transition Management and cfg80211 connect command For now, this is not enforcing cfg80211 reassociation since the needed changes do not yet exist in the upstream kernel. Once those changes are accepted, the TODO note in the test case can be addressed.
