I was trying to guess the use case for the vlan which has implemented
rtnl_link api :

For sending parameters to driver:
# ip link set <vlan-iface-name> up multicast ...... type vlan id
<vlan-id> reorder_hdr on

ingress-qos-map <...> egress-qos-map <...>

In such case, I think the link_util's private parse_opt function will
be invoked to parse link's private configurable parameters.  These
parameters along with the standard set of parameters (name, multicast,
promisc etc) are then sent to driver through rtnl_talk function .

Similarly, for reading values from driver:

# ip addr show dev <vlan-iface-name>

does it require "type" field similar to "ip link set"?

Is this understanding correct?

How does a link type corresponding to VLAN driver gets added into
linkutil_list, so that ip will correctly call functions specific to
VLAN driver?

I was looking at latest release of iproute2, in which I could not
locate fill_xstats. Can you help me to locate this?

Thanks and Regards,
