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>
