    • getAddedTlvsList

      public List<TlvEntry> getAddedTlvsList()
       This config allows additional TLVs to be included in the upstream PROXY protocol
 V2 header. Unlike ``pass_through_tlvs``, which passes TLVs from the downstream request,
 ``added_tlvs`` provides an extension mechanism for defining new TLVs that are included
 with the upstream request. These TLVs may not be present in the downstream request and
 can be defined at either the transport socket level or the host level to provide more
 granular control over the TLVs that are included in the upstream request.

 Host-level TLVs are specified in the ``metadata.typed_filter_metadata`` field under the
 ``envoy.transport_sockets.proxy_protocol`` namespace.

 **Precedence behavior**:

 - When a TLV is defined at both the host level and the transport socket level, the value
   from the host level configuration takes precedence. This allows users to define default TLVs
   at the transport socket level and override them at the host level.
 - Any TLV defined in the ``pass_through_tlvs`` field will be overridden by either the host-level
   or transport socket-level TLV.

 If there are multiple TLVs with the same type, only the TLVs from the highest precedence level
 will be used.
