From 6e1b1b246096fe04467f928973487fa47afaf2cc Mon Sep 17 00:00:00 2001 From: Eliad Peller Date: Thu, 26 Jan 2012 13:36:05 +0200 Subject: mac80211: send null packet on active (psm) reconfiguration The sta might be in psm against the ap (e.g. because this was the before a hw restart), so we explicitly send a null packet in order to make sure it'll sync against the ap (and get out of psm).
