Add IFLA_PARENT_DEV_NAME / IFLA_PARENT_DEV_BUS_NAME to links

Browse Source 
These attributes are supported since kernel v5.14 (see [1]). Here's
what iproute2 shows:

```
$ ip -d link show eth0
4: eth0: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 65535 qdisc pfifo_fast state UP mode DEFAULT group default qlen 1000
    ... parentbus virtio parentdev virtio0
```
