Subject: Re: [PATCH net] net: dsa: mt7530: don't change PVC_EG_TAG when CPU
 port becomes VLAN-aware

One last thing. Specific to MT7530 switch in MT7621 SoC, if port@5 is 
the only CPU port defined on the devicetree, frames sent from DSA master 
appears malformed on the user port. Packet capture on computer connected 
to the user port is attached.

The ARP frames on the pcapng file are received on the DSA master, I 
captured them with tcpdump, and put it in the attachments. Then I start 
pinging from the DSA master and the malformed frames appear on the 
pcapng file.

It'd be great if you could take a look this final issue.
