Add new UAPI to support the mac address from vdpa tool
Function vdpa_nl_cmd_dev_attr_set_doit() will get the
new MAC address from the vdpa tool and then set it to the device.
The usage is: vdpa dev set name vdpa_name mac **:**:**:**:**:**
Here is example:
root@L1# vdpa -jp dev config show vdpa0
{
"config": {
"vdpa0": {
"mac": "82:4d:e9:5d:d7:e6",
"link ": "up",
"link_announce ": false,
"mtu": 1500
}
}
}
root@L1# vdpa dev set name vdpa0 mac 00:11:22:33:44:55
root@L1# vdpa -jp dev config show vdpa0
{
"config": {
"vdpa0": {
"mac": "00:11:22:33:44:55",
"link ": "up",
"link_announce ": false,
"mtu": 1500
}
}
}

This commit cleans up the uapi for vhost_vdpa by
better naming some of the enums which report blk
information to user space, and they are not
in any official releases yet.
