1. the patch 0001* is for setting single port into 802.1AD(QinQ) mode,
before this patch, the function dsa_slave_vlan_rx_add_vid didn't pass 
the parameter "proto" to next port level, so switch's port can't get
parameter "proto"
  after applying this patch, the following command can be supported:
  ip link set br0 type bridge vlan_protocol 802.1ad
  ip link add link swp1 name swp1.100 type vlan protocol 802.1ad id 100

2. the patch 0002* 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.

3. Version log
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

Please defer new feature changes, like this, until the net-next tree is open
again.  It is closed right now.

Thank you.
