From 6c40063d5a61cd245e0828088024fc1eb02a2083 Mon Sep 17 00:00:00 2001 From: Stanislaw Gruszka Date: Fri, 18 Nov 2016 10:43:59 +0100 Subject: [PATCH] rt2800: use RTS/CTS protection instead of CTS-to-self Change default to RTS/CTS protection. This has a cost of transmitting one more control frame (RTS) however protect us from traffic from hidden node. On station mode will use CTS-to-self if AP will configure that for the network.
