Subject: [PATCH 08/10] rt2800: use RTS/CTS protection instead of CTS-to-self
Date: Wed,  2 Nov 2016 15:11:03 +0100	[thread overview]
Message-ID: <1478095865-8651-9-git-send-email-sgruszka@redhat.com> (raw)
In-Reply-To: <1478095865-8651-1-git-send-email-sgruszka@redhat.com>

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.
