From 8782b41d13c8e5f9a201477d3c15edf9fe7c372c Mon Sep 17 00:00:00 2001 From: Vivek Natarajan Date: Mon, 30 Mar 2009 14:17:00 +0530 Subject: [PATCH] ath9k: No need to abort Rx path when autosleep is enabled. For chipsets supporting autosleep feature, there is no need to abort Rx engine since they are capable of automatically going back to sleep after receiving a packet.
