bridge: T6125: support 802.1ad (ethertype 0x88a8) VLAN filtering

Browse Source 
Linux bridge uses EtherType 0x8100 by default. In some scenarios, an EtherType
value of 0x88A8 is required.

Reusing CLI command from VIF-S (QinQ) interfaces:
  set interfaces bridge br0 protocol 802.1ad

(cherry picked from commit a7f2e520cbf8b24ccb5e266b5d4c739588aed48e)

Define used ethertype of bridge interface.
Ethertype ``0x8100`` is used for ``802.1q`` and ethertype ``0x88a8`` is used
for ``802.1ad``.
The default is ``802.1q``.
