From: Xinming Hu Date: Fri, 2 Sep 2016 07:35:06 +0000 (+0530) Subject: mwifiex: add manufacturing mode support X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=cf5383b088d07f304d189986fdbd4efbd7d41538;p=GitHub%2Fmoto-9609%2Fandroid_kernel_motorola_exynos9610.git mwifiex: add manufacturing mode support By default normal mode is chosen when driver is loaded. This patch adds a provision to choose manufacturing mode via module parameters. Below command loads driver in manufacturing mode insmod mwifiex.ko mfg_mode=1.
