This series implements the proposed fc_host feature of virtio-scsi.
The first patch updates the data structure changes according to the spec
proposal; the second patch actually implements the operations.
Fam Zheng (2):
virtio_scsi: Add fc_host definitions
virtio_scsi: Implement fc_host
driv
This implements the VIRTIO_SCSI_F_FC_HOST feature by reading the config
fields and presenting them as sysfs fc_host attributes. The config
change handler is added here because primary_active will toggle during
migration.

During initial implementation, tape support was included but not

used actively, we want to remove it and we will add back if there
are any request in future for SRR support.
