This is a note to let you know that I have just added a patch titled iwlwifi: dvm: run INIT firmware again upon .start() to the linux-3.16.y-queue branch of the 3.16.y-ckt extended stable tree which can be found at: http://kernel.ubuntu.com/git?p=ubuntu/linux.git;a=shortlog;h=refs/heads/linux-3.16.y-queue This patch is scheduled to be released in version 3.16.7-ckt10. If you, or anyone else, feels it should not be added to this tree, please reply to this email. For more information about the 3.16.y-ckt tree, see https://wiki.ubuntu.com/Kernel/Dev/ExtendedStable Thanks. -Luis ------ From bf5ac2779b8606495fba178306086582a5a244f4 Mon Sep 17 00:00:00 2001 From: Emmanuel Grumbach <emmanuel.grumbach@intel.com> Date: Mon, 16 Mar 2015 09:08:07 +0200 Subject: iwlwifi: dvm: run INIT firmware again upon .start() commit 9c8928f5176766bec79f272bd47b7124e11cccbd upstream. The assumption before this patch was that we don't need to run again the INIT firmware after the system booted. The INIT firmware runs calibrations which impact the physical layer's behavior. Users reported that it may be helpful to run these calibrations again every time the interface is brought up. The penatly is minimal, since the calibrations run fast.
