------------------- This is a commit scheduled for the next v2.6.34 longterm release. http://git.kernel.org/?p=linux/kernel/git/paulg/longterm-queue-2.6.34.git If you see a problem with using this for longterm, please comment. -------------------
commit aa3d7eef398dd4f29045e9889b817d5161afe03e upstream.
During the association, the regulatory is updated by country IE that reaps the previously found beacons. The impact is that after a STA disconnects *or* when for any reason a regulatory domain change happens the beacon hint flag is not cleared therefore preventing future beacon hints to be learned. This is important as a regulatory domain change or a restore of regulatory settings would set back the passive scan and no-ibss flags on the channel. This is the right place to do this given that it covers any regulatory domain change.
