From edcdf8b21ac920e06b4180246123fe43b022e020 Mon Sep 17 00:00:00 2001 From: Ron Rindjunsky Date: Thu, 15 May 2008 13:53:55 +0800 Subject: mac80211: separate Tx and Rx MCS when configuring HT This patch follows the 11n spec in separation between Tx and Rx MCS capabilities. Up until now, when configuring the HT possible set of Tx MCS only Rx MCS were considered, assuming they are the same as the Tx MCS. This patch fixed this by looking at low level driver Tx capabilities. Signed-off-by: Ron Rindjunsky Signed-off-by: Tomas Winkler Signed-off-by: John W.

For example the configuration (8, +1), (primary channel 8, extension channel 12) isn't permitted in U.S., but (8, -1), (primary channel 8, extension channel 4) is. When FAT channel configuration is not permitted, FAT channel should be reported as not supported in the capabilities of the HT IE in association request. And sssociation is performed on 20Mhz channel. Signed-off-by: Emmanuel Grumbach Signed-off-by: Tomas Winkler Signed-off-by: John W.
