From 692af5da779e018fc6a3b480b67adb33e3c6e1f0 Mon Sep 17 00:00:00 2001 From: Patrick McHardy Date: Wed, 7 May 2008 22:37:29 +0800 Subject: [PATCH] [HIFN]: Have HW invalidate src and dest descriptors after processing The descriptors need to be invalidated after processing for ring cleanup to work properly and to avoid using an old destination descriptor when the src and cmd descriptors are already set up and the dst descriptor isn't.
