This series add support for creating VLAN interface over HSR or
PRP interface. Typically industrial networks uses VLAN in
deployment and this capability is needed to support these
networks.
This is tested using two TI AM572x IDK boards connected back
to back over CPSW ports (eth0 and eth1).
Following is the setup

Following tests:-
- create hsr or prp interface and ping the interface IP address
and verify ping is successful.
- Create 2 VLANs over hsr or prp interface on both IDKs (VID 100 and
101). Ping between the IP address of the VLAN interfaces
- Do iperf UDP traffic test with server on one IDK and client on the
other. Do this using 100 and 101 subnet IP addresses
- Dump /proc/net/vlan/{hsr|prp}0.100 and verify frames are transmitted
and received at these interfaces.
- Delete the vlan and hsr/prp interface and verify interfaces are
removed cleanly.
