From ad932f046fbe9839479350e7b88082a7d1dea498 Mon Sep 17 00:00:00 2001 From: Arik Nemtsov Date: Thu, 27 Nov 2014 09:44:55 +0200 Subject: cfg80211: leave invalid channels on regdomain change When the regulatory settings change, some channels might become invalid. Disconnect interfaces acting on these channels, after giving userspace code a grace period to leave them. This mode is currently opt-in, and not all interface operating modes are supported for regulatory-enforcement checks. A wiphy that wishes to use the new enforcement code must specify an appropriate regulatory flag, and all its supported interface modes must be supported by the checking code.
