c9027d8f44 SRIOV NIC offload feature discovery
Adding functionality to libvirt that will allow it
query the ethtool interface for the availability
of certain NIC HW offload features

Here is an example of the feature XML definition:

<device>
<name>net_eth4_90_e2_ba_5e_a5_45</name>
  <path>/sys/devices/pci0000:00/0000:00:03.0/0000:08:00.1/net/eth4</path>
  <parent>pci_0000_08_00_1</parent>
  <capability type='net'>
    <interface>eth4</interface>
    <address>90:e2:ba:5e:a5:45</address>
    <link speed='10000' state='up'/>
    <feature name='rx'/>
    <feature name='tx'/>
    <feature name='sg'/>
    <feature name='tso'/>
    <feature name='gso'/>
    <feature name='gro'/>
    <feature name='rxvlan'/>
    <feature name='txvlan'/>
    <feature name='rxhash'/>
    <capability type='80203'/>
  </capability>
</device>

f3271f4cb3 Add unique_id to nodedev output
Add an optional unique_id parameter to nodedev.  Allows for easier lookup
and display of the unique_id value in order to document for use with
scsi_host code.

16ebf10f34 nodedev: Introduce <pci-express/> to PCI devices
This new element is there to represent PCI-Express capabilities
of a PCI devices, like link speed, number of lanes, etc.

0311ef3d65 node_device: Expose link state & speed
While exposing the info under <interface/> in previous patch works, it
may work only in cases where interface is configured on the host.
However, orchestrating application may want to know the link state and
speed even in that case. That's why we ought to expose this in nodedev
XML too:

virsh # nodedev-dumpxml net_eth0_f0_de_f1_2b_1b_f3
<device>
  <name>net_eth0_f0_de_f1_2b_1b_f3</name>
  <path>/sys/devices/pci0000:00/0000:00:19.0/net/eth0</path>
  <parent>pci_0000_00_19_0</parent>
  <capability type='net'>
    <interface>eth0</interface>
    <address>f0🇩🇪f1:2b:1b:f3</address>
    <link speed='1000' state='up'/>
    <capability type='80203'/>
  </capability>
</device>

1c70277886 nodedev: Export NUMA node locality for PCI devices
A PCI device can be associated with a specific NUMA node. Later, when
a guest is pinned to one NUMA node the PCI device can be assigned on
different NUMA node. This makes DMA transfers travel across nodes and
thus results in suboptimal performance. We should expose the NUMA node
locality for PCI devices so management applications can make better
decisions.

0bdefd9b04 nodedev: Resolve Relax-NG validity error
Commit id 'c4a4603de' added an output <path> to the nodedev xml, but
did not update the schema.

This resulted in the failure of the 'virt-xml-validate' on a file
generated by 'virsh nodedev-dumpxml pci_0000_00_00_0' (for example).

This was found/seen by running autotest on my host.

8807b28559 nodedev: add iommuGroup to node device object
This includes adding it to the nodedev parser and formatter, docs, and
test.

An example of the new iommuGroup element that is a part of the output
from "virsh nodedev-dumpxml" (virNodeDeviceGetXMLDesc()):

  <device>
    <name>pci_0000_02_00_1</name>
    <capability type='pci'>
    ...
      <iommuGroup number='12'>
        <address domain='0x0000' bus='0x02' slot='0x00' function='0x0'/>
        <address domain='0x0000' bus='0x02' slot='0x00' function='0x1'/>
      </iommuGroup>
    </capability>

This enrichs HBA's xml by dumping the number of max vports and

    <vports>5</vports>
  </capability>

cc17f09246 npiv: Expose fabric_name outside
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)
