From 42d97a599eb6b2aab3a401b3e5799a399d6c7652 Mon Sep 17 00:00:00 2001 From: Johannes Berg Date: Thu, 8 Nov 2012 18:31:02 +0100 Subject: cfg80211: remove remain-on-channel channel type As mwifiex (and mac80211 in the software case) are the only drivers actually implementing remain-on-channel with channel type, userspace can't be relying on it. This is the case, as it's used only for P2P operations right now. Rather than adding a flag to tell userspace whether or not it can actually rely on it, simplify all the code by removing the ability to use different channel types. Leave only the validation of the attribute, so that if we extend it again later (with the needed capability flag), it can't break userspace sending invalid data.
