Subject: [PATCH 5/9] rt2800: tune TX_RTS_CFG config
Date: Fri, 6 Jan 2017 14:05:14 +0100 [thread overview]
Message-ID: <1483707918-31480-6-git-send-email-sgruszka@redhat.com> (raw)
In-Reply-To: <1483707918-31480-1-git-send-email-sgruszka@redhat.com>
Enable RTS frame retry fall-back and limit number of RTS retries to 7
what is default number of retries for small frames. As RTS/CTS is used
for TXOP protection, those settings prevent posting lots of RTS
frames when remote station do not response with CTS at the moment. After
sending 7 RTS's the HW will start back-off mechanism and after it will
start posing RTS again to get access to the medium.
