From 860eca2b2bf90c513c1d6d9f889b3e0801e7ac08 Mon Sep 17 00:00:00 2001 From: Vasu Dev Date: Tue, 27 Sep 2011 21:38:18 -0700 Subject: [PATCH] [SCSI] fcoe: setup default initial value for DDP threshold Currently fcoe_ddp_min doesn't have default value so by default not used, so setting up default value as 4k as this works better by avoiding overhead of programing DDP for small IOs.
