From 05bfe3d2a5794cc9e9b8119f36d1d7848ecd8967 Mon Sep 17 00:00:00 2001 From: Rajkumar Manoharan Date: Thu, 15 Sep 2011 19:02:53 +0530 Subject: [PATCH] ath9k: load noise floor from history after the full chip reset Currently during the full reset, the nf calibration is always restarted from the defaults. The noise floor history buffers are never be used again after the scan and ath reset. This patch ensures that nf histories are always be used that helps to improve the signal quality on congested environment Signed-off-by: Rajkumar Manoharan Signed-off-by: John W.
