Setter method for unknown_subtlv, mapped from YANG variable /network_instances/network_instance/protocols/protocol/ospfv2/areas/area/lsdb/lsa_types/lsa_type/lsas/lsa/opaque_lsa/traffic_engineering/tlvs/tlv/node_attribute/sub_tlvs/sub_tlv/unknown_subtlv (container)
    If this variable is read-only (config: false) in the
    source YANG file, then _set_unknown_subtlv is considered as a private
    method. Backends looking to populate this variable should
    do so via calling thisObj._set_unknown_subtlv() directly.

    YANG Description: An unknown SubTLV within the context. Unknown Sub-TLV
are defined to be the set of SubTLVs that are not modelled
by the OpenConfig schema, or are unknown to the local system
such that it cannot decode their value.
