From b50a62bb39c66e6ed5f1f581bb32644936f08cf3 Mon Sep 17 00:00:00 2001 From: Arik Nemtsov Date: Tue, 27 Nov 2012 08:44:56 +0200 Subject: [PATCH] wlcore: initialize per-link FW freed blocks correctly When a link is allocated, sometimes the "freed packets" counter in FW is non zero, but we always assumed it is. This caused us to incorrectly account FW allocated blocks in some cases. When operating in AP mode, this bug caused some stations to never come back from PSM.
