3.3-stable review patch. If anyone has any objections, please let me know.
------------------ From: Felix Fietkau <[email protected]> commit 6741e7f048dacc92e37c5d724ff5c64e45f6c2c9 upstream. The broken check leads to rate control attempting to use HT40 while the driver is configured for HT20. This leads to interesting hardware issues. HT40 can only be used if the channel type is either HT40- or HT40+ and if the channel type of the cell matches the local type. Signed-off-by: Felix Fietkau <[email protected]> Signed-off-by: John W.
