From 716f9392e2b84cacc18cc11f7427cb98adeb1c3d Mon Sep 17 00:00:00 2001 From: "Luis R. Rodriguez" Date: Thu, 22 Jan 2009 15:05:51 -0800 Subject: [PATCH] cfg80211: pass more detailed regulatory request information on reg_notifier() Drivers may need more information than just who set the last regulatory domain, as such lets just pass the last regulatory_request receipt. To do this we need to move out to headers struct regulatory_request, and enum environment_cap. While at it lets add documentation for enum environment_cap. Signed-off-by: Luis R.
