From 8b60b07805d557542160d852874fa6a1b969184e Mon Sep 17 00:00:00 2001 From: "Luis R. Rodriguez" Date: Tue, 11 Oct 2011 10:59:02 -0700 Subject: cfg80211: process regulatory DFS region for countries The wireless-regdb now has support for mapping a country to one DFS region. CRDA sends this to us now so process it so we can provide that hint to drivers. This will later be used by code for processing DFS in a way that meets the criteria for the DFS region the country belongs to. Signed-off-by: Luis R. Rodriguez Signed-off-by: John W.

This allows users to disable features such as HT, HT40, and to modify the MCS, AMPDU, and AMSDU settings for drivers that support it. The MCS, AMPDU, and AMSDU features that may be disabled are are reported in the phy-info netlink message as a mask. Attemping to disable features that are not supported will take no affect, but will not return errors. This is to aid backwards compatibility in user-space apps that may not be clever enough to deal with parsing the the capabilities mask. This patch only enables the infrastructure. An additional patch will enable the feature in mac80211. Signed-off-by: Ben Greear Signed-off-by: John W.
