Currently only one EtherType can be configured for pushing in tunnels because EtherType is configured using SPVID.et_vlan for tunnel port. This behavior is forbidden by comparing mlxsw_sp_nve_config struct for each new tunnel, the struct contains 'ethertype' field which means that only one EtherType is legal at any given time. Remove 'ethertype' field to allow creating VxLAN devices with different bridges. To allow using several types of VxLAN bridges at the same time, the EtherType should be determined at the egress port. This behavior is achieved by setting SPVID to decide which EtherType to push at egress and for each local_port which is member in 802.1ad bridge, set SPEVET.et_vlan to ether_type1 (i.e., 0x88A8). Use switchdev_ops->init() to set different mlxsw_sp_bridge_ops for different ASICs in order to be able to split the behavior when port joins / leaves an 802.1ad bridge in different ASICs.
