From 71de1f3dd14e3e39cef929506a9526779f5a447d Mon Sep 17 00:00:00 2001 From: "Cahill, Ben M" Date: Wed, 8 Mar 2006 03:02:27 +0800 Subject: [PATCH] ipw2200: Enables the "slow diversity" algorithm This forces one antenna or the other, if the background noise is significantly quieter in one than the other. It favors the quieter antenna, and won't kick in unless the difference is significant. Signed-off-by: Cahill, Ben M Signed-off-by: Zhu Yi Signed-off-by: John W.
