From 53c5a099b8fd45632f4021f0a908b43aabe883fc Mon Sep 17 00:00:00 2001 From: Gabor Juhos Date: Mon, 14 Oct 2013 21:59:52 +0200 Subject: rt2x00: rt2800lib: autodetect 5GHz band support If the RF chip supports more than 14 channels that indirectly means that it supports the 5GHz band. Use this fact to enable 5GHz band support instead of setting SUPPORT_BAND_5GHZ separately for each RF chip. Also move the setup code of the 2GHz band to the same place.
