From 42cb87a101c3fd0e080e9605ee70275efdcc8280 Mon Sep 17 00:00:00 2001 From: Felix Fietkau Date: Sat, 10 Aug 2013 15:59:15 +0200 Subject: [PATCH] ath9k: fix rx descriptor related race condition commit e96542e55a2aacf4bdeccfe2f17b77c4895b4df2 upstream. Similar to a race condition that exists in the tx path, the hardware might re-read the 'next' pointer of a descriptor of the last completed frame. This only affects non-EDMA (pre-AR93xx) devices. To deal with this race, defer clearing and re-linking a completed rx descriptor until the next one has been processed. Signed-off-by: Felix Fietkau Signed-off-by: John W.
