From b0159308b5be6952577356c06358752b5ebfb86d Mon Sep 17 00:00:00 2001 From: Jouni Malinen Date: Sat, 29 Mar 2014 09:24:22 +0200 Subject: [PATCH] tests: ACS for 40 MHz channels, on 5 GHz, and for VHT The 5 GHz cases are not yet complete due to missing mac80211_hwsim functionality. The current test cases allow the ACS operation to fail for those cases.
