Subject: [PATCH v6 0/3] Add 802.1AD protocol support for dsa switch and ocelot driver

From: "hongbo.wang" <hongbo.wang@....com>

1. Overview 
a) 0001* is for support to set dsa slave into 802.1AD(QinQ) mode.
b) 0002* is for vlan_proto support for br_switchdev_port_vlan_add and br_switchdev_port_vlan_del.
c) 0003* is for setting QinQ related registers in ocelot switch driver, after applying this patch, the switch(VSC99599)'s port can enable or disable QinQ mode.

2. Version log
v6:
a) put the code for switchdev into single patch
b) change code according to latest mainline

v5:
a) add devlink to enable qinq_mode of ocelot's single port 
b) modify br_switchdev_port_vlan_add to pass bridge's vlan_proto to port driver 
c) enable NETIF_F_HW_VLAN_STAG_FILTER in ocelot driver

v4:
a) modify slave.c to support "ip set br0 type bridge vlan_protocol 802.1ad"
b) modify ocelot.c, if enable QinQ, set VLAN_AWARE_ENA and VLAN_POP_CNT per
   port when vlan_filter=1

v3: combine two patches to one post

hongbo.wang (3):
  net: dsa: Add protocol support for 802.1AD when adding or deleting
    vlan for dsa switch port
  net: switchdev: Add VLAN protocol support for switchdev port
  net: dsa: ocelot: Add support for QinQ Operation
