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

    YANG Description: An unknown TLV within the context. Unknown TLVs are
defined to be the set of TLVs that are not modelled
within the OpenConfig model, or are unknown to the
local system such that it cannot decode their value.
