This enrichs HBA's xml by dumping the number of max vports and
vports in use. Format is like:
<capability type='vport_ops'>
<max_vports>164</max_vports>
<vports>5</vports>
</capability>
* docs/formatnode.html.in: (Document the new XML)
* docs/schemas/nodedev.rng: (Add the schema)
* src/conf/node_device_conf.h: (New member for data.scsi_host)
* src/node_device/node_device_linux_sysfs.c: (Collect the value of
max_vports and vports)
This patch is to expose the fabric_name of fc_host class, which
might be useful for users who wants to known which fabric the
(v)HBA connects to.
The patch also adds the missed capabilities' XML schema of scsi_host,
(of course, with fabric_wwn added), and update the documents
(docs/formatnode.html.in)
Coupled with the recent virsh nodedev-* doc patch, this should now
give a better picture of libvirt node device handling.
* docs/formatnode.html.in: Fill in page.
