From 9399627f340794baebf7e4581470ccb92f019acc Mon Sep 17 00:00:00 2001 From: James Smart Date: Sun, 24 Aug 2008 21:50:30 -0400 Subject: [SCSI] lpfc 8.2.8 : Add MSI-X support Add support for MSI-X Multi-Message interrupts. We use different vectors for fast-path interrupts (i/o) and slow-patch interrupts (discovery, etc).
