From 443be7960be77f3345b44491c700ae4471b0fe57 Mon Sep 17 00:00:00 2001 From: Dhananjay Phadke Date: Mon, 17 Mar 2008 19:59:48 -0700 Subject: netxen: improve msi support Recent netxen firmware has new scheme of generating MSI interrupts, it raises interrupt and blocks itself, waiting for driver to unmask. This reduces chance of spurious interrupts. The driver will be able to deal with older firmware as well.
