Subject: [PATCH v3 1/2] net: dsa: Add protocol support for 802.1AD when adding or deleting vlan for dsa switch and port
From: "hongbo.wang" <hongbo.wang@....com>
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.
