From 72a801103f07182c0a4f3a761caa62b4ab8eb4e5 Mon Sep 17 00:00:00 2001 From: Bruno Randolf Date: Wed, 10 Nov 2010 12:51:01 +0900 Subject: [PATCH] ath5k: Add support for antenna configuration Support setting the antenna configuration via cfg/mac80211. At the moment only allow the simple pre-defined configurations we already have (fixed antenna A/B or diversity), but more advanced settings are possible to implement.
