The "hw vlan offload" feature being broken on non-mt7621/7622 devices is 
already established, hence this patch disabling it for the 
non-mt7621/7622 devices. I still don't understand why you're mentioning 
it in this way, unless you're trying to say something else?

Could you also not trim the relevant parts of the mail on your response. 
It's getting hard to keep track of the conversation.
