Subject: [PATCH] net: dsa: Add protocol support for 802.1AD when adding or deleting vlan for dsa switch and port

From: "hongbo.wang" <[email protected]>

the following command will be supported:
Add VLAN:
ip link add link swp1 name swp1.100 type vlan protocol 802.1ad id 100
Delete VLAN:
ip link del link swp1 name swp1.100

when adding vlan, this patch only set protocol for user port,
cpu port don't care it, so set parameter proto to 0 for cpu port.

My previous feedback has been partially addressed, can you also post the
switch driver changes that are going to implement the driver side
changes? Presumably you must act on the 802.1AD programming request in
the switch driver somehow, right?

Hi Florian,

Thanks for your reply!

I had posted my patch for switch port driver, the email title is "net: dsa: ocelot: Add support for QinQ Operation",

Best Regards!
