From 7d1620451d4994d767bdcb23907209b21603d185 Mon Sep 17 00:00:00 2001 From: Johannes Berg Date: Thu, 17 Sep 2015 15:54:47 +0200 Subject: iwlwifi: nvm: fix up phy section when reading it 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 on MIMO disabled bit which is correct in the OTP and set to disabled. This fixes the previous workaround "force 1x1 antenna in Series 8000".
