From 02fabb0eafde901ae51532ad15fdd4737b7d71e3 Mon Sep 17 00:00:00 2001 From: Juuso Oikarinen Date: Thu, 19 Aug 2010 04:41:15 +0200 Subject: [PATCH] wl1271: Enable/disable 11a support based on INI configuration Instead of hardcoding 11a support, enable/disable driver support based on the dual-mode-select parameter in the nvs-file general paramters.
