Subject: iwlwifi: nvm: remove mac address byte swapping in 8000 family
From: Liad Kaufman <[email protected]>
commit be88a1ada9b97bb016196b7f4a1fc2fe2f798529 upstream.
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.
