From 87f6eaffd732bc20b5a02e9f36b86f67310d8129 Mon Sep 17 00:00:00 2001 From: "James.Smart@Emulex.Com" Date: Sat, 25 Jun 2005 10:34:13 -0400 Subject: [PATCH] [SCSI] lpfc: Fix error loading on sparc Bug reported via SourceForge - lpfc does not load on sparc. The lpfc driver must byteswap all FCP IOCBs to recover the data into cpu native format.
