From fcfa0a32c767219c1bdad621ef4a3aff1904cbbd Mon Sep 17 00:00:00 2001 From: Michael Chan Date: Mon, 20 Mar 2006 22:28:41 -0800 Subject: [TG3]: Add new one-shot MSI handler Support one-shot MSI on 5787. This one-shot MSI idea is credited to David Miller. In this mode, MSI disables itself automatically after it is generated, saving the driver a register access to disable it for NAPI.
