[PATCH v2 0/2] virtio-scsi: Implement FC_HOST feature
v2: Fix endianness of WWNN/WWPN. [Paolo]
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.

Is the endianness correct for big-endian host here?
