From e4019e7f95302c45fad5c35d62c9b3ca8fc30fb2 Mon Sep 17 00:00:00 2001 From: Stanislaw Gruszka Date: Fri, 6 Jan 2017 14:05:14 +0100 Subject: [PATCH] rt2800: tune TX_RTS_CFG config 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.
