From aebc0a88ddf514ef2b3cdba0b3f14883b8b0e339 Mon Sep 17 00:00:00 2001 From: Felix Fietkau Date: Wed, 14 Mar 2012 16:40:27 +0100 Subject: [PATCH] ath9k_hw: clean up ath9k_hw_setuprxdesc The ATH9K_HW_CAP_AUTOSLEEP check is bogus, the rx status area needs to be cleared on all non-EDMA PCI/AHB based chipsets anyway. Limit the memset to the rx status area to improve performance. Signed-off-by: Felix Fietkau Signed-off-by: John W.
