From adc89595732b92f78940fc0ccdb52afaec582a48 Mon Sep 17 00:00:00 2001 From: Amitkumar Karwar Date: Wed, 27 Apr 2011 19:13:11 -0700 Subject: [PATCH] mwifiex: check firmware capabilities while initialising 5GHz band parameters There are some SD8787 cards which don't support 5GHz band. Therefore initialise 5GHz band parameters only if hardware supports the band. Signed-off-by: Amitkumar Karwar Signed-off-by: Bing Zhao Signed-off-by: John W.
