2015-10-05iwlwifi: nvm: force 1x1 antenna in Series 8000Moshe Harel1-1/+14
This is a workaround to an OTP bug. In Series 8000 1x1, the OTP 0xA052 defines 2x2 antenna configuration. This workaround overrides the decision based on HW id and MIMO disabled bit which is correct in the OTP and set to disabled.

2015-07-12iwlwifi: nvm: remove mac address byte swapping in 8000 familyLiad Kaufman1-7/+5
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.

The driver wasn't reading the NVM properly. While this didn't lead to any issue until now, it seems that there is an old version of the NVM in the wild. In this version, the A band channels appear to be valid but the SKU capabilities (another field of the NVM) says that A band isn't supported at all. With this specific version of the NVM, the driver would think that A band is supported while the HW / firmware don't. This leads to asserts.
