From 5da61410054d125e63aeab9cc7a11874a69465c0 Mon Sep 17 00:00:00 2001 From: Anil Ravindranath Date: Tue, 16 Nov 2010 13:43:41 -0800 Subject: [SCSI] pmcraid: disable msix and expand device config entry Firmware requires a larger configuration entry size than the driver currently allows, and MSI-X pretty much doesn't work with current FW, so disable it for now.
