From 1956cf6fa1039647327ef333dc09b43775907305 Mon Sep 17 00:00:00 2001 From: Gonglei Date: Thu, 29 Jan 2015 15:08:53 +0800 Subject: vhost-scsi: expose the TYPE_FW_PATH_PROVIDER interface In the way, we can make the bootindex property take effect. At the meanwhile, the firmware path name of vhost-scsi is "channel@channel/vhost-scsi@target,lun". Signed-off-by: Gonglei Acked-by: Michael S.
