Subject: [PATCH v2 7/9] rt2800: use RTS/CTS protection instead of CTS-to-self
Date: Fri, 18 Nov 2016 10:43:59 +0100 [thread overview]
Message-ID: <1479462241-9299-8-git-send-email-sgruszka@redhat.com> (raw)
In-Reply-To: <1479462241-9299-1-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.
