Subject: [PATCH 10/10] iwlwifi: nvm: remove mac address byte swapping in 8000 family
Date: Sun, 12 Jul 2015 20:08:20 +0300 [thread overview]
Message-ID: <1436720900-18588-10-git-send-email-emmanuel.grumbach@intel.com> (raw)
In-Reply-To: <1436720814.17999.2.camel@intel.com>
From: Liad Kaufman <liad.kaufman@intel.com>
This fixes the byte order copying in the MAO (Mac Override
Section) section from the PNVM, as the byte swapping is not
required anymore in the 8000 family. Due to the byte
swapping, the driver was reporting an incorrect MAC
adddress.
