From 01bdcb626f80838f55ec2af993daef50b9c59c49 Mon Sep 17 00:00:00 2001 From: Robert Love Date: Mon, 25 Mar 2013 11:00:26 -0700 Subject: [PATCH 1/5] bnx2fc: Make the fcoe_cltr the SCSI host parent The fcoemon userspace daemon is searching for the a hostX under the the /sys/bus/fcoe/devices/ctlrX/ entries. When interfaces created using fcoe_sysfs and fcoe.ko this linkage is setup correctly, but bnx2fc is not doing the same thing and therefore fcoemon does not create the fcoe interface for bnx2fc. This patch sets up the correct linkage for bnx2fc such that fcoemon will work correctly with fcoe_sysfs and bnx2fc.

The problem is that for VN2VN mode the discovery layer is initialized as if it were in 'fabric' mode and it is not re-configured when the mode is changed to 'vn2vn'. This patch splits out code that needs to be initialized once and code that can, and should be, re-configured when the mode changes. Additionally this patch makes that change so that the discovery layer can be reconfigured to the libfcoe implementation when in 'vn2vn' mode.
