This change set introduces data structure changes required for multiple vlan aware bridge functionality. A new structure zebra_l2_bridge_if encapsulates the vlan to access_bd association of the bridge. A vlan_table hash_table is used to record each instance of the vlan to access_bd of the bridge via zebra_l2_bridge_vlan structure. vxlan iftype derivation: netlink attribute IFLA_VXLAN_COLLECT_METADATA is used to derive the iftype of the vxlan device. If the attribute is present, then the vxlan interface is treated as single vxlan device, otherwise it would default to traditional vxlan device. zebra_vxlan_check_readd_vtep, zebra_vxlan_dp_network_mac_add/del is modified to be vni aware. mac_fdb_read_for_bridge - is modified to be (vlan, bridge) aware Signed-off-by: Sharath Ramamurthy <sramamurthy@nvidia.com>
