similar to: [PATCH v2] tcm_vhost: Multi-target support

In order to take advantages of Paolo's multi-queue virito-scsi, we need multi-target support in tcm_vhost first. Otherwise all the requests go to one queue and other queues are idle. This patch makes: 1. All the targets under the wwpn is seen and can be used by guest. 2. No need to pass the tpgt number in struct vhost_scsi_target to tcm_vhost.ko. Only wwpn is needed. 3. We can always pass

From: Nicholas Bellinger <nab at linux-iscsi.org> Hello KVM + QEMU folks, This is -v5 of the in-flight tcm_vhost fabric driver for KVM host virtualized target support using the in-kernel storage stack with for-3.6 code. The changes since -v4 have been pretty minimal. A new GET_ABI_VERSION ioctl has been added as requested by Anthony & Co, and after some back <-> forth on the

From: Gonglei <arei.gonglei at huawei.com> In order to support to assign a boot order for vhost-scsi device, we should get the tpgt for user level (such as Qemu). and at present, we only support the minimum tpgt can boot.
