NDNLP-TLV exists only in NFD, but it's necessary to implement NDNLPv2 in ndn-cxx because some features, such as Nack, can be used by applications.
Unlike LocalControlHeader, management/ is not the right place to put NDNLPv2 abstractions, because many NDNLPv2 features are not limited for local use, and thus do not fit in management.
My proposal is to create a new lp/ subdirectory for NDNLPv2.
The files will be:
lp/tlv.hpp: TLV-TYPE codeslp/sequence.hpp: typedef forSequencevalue typelp/nack-reason.hpp:NackReasonbase type, a Doxygen comment to defineNackReasonConcreteconcept and a concept checklp/detail/nack-reason-decl.hpp: templates and specializations used for declaring NackReasonslp/duplicate.hpp: typedef forDuplicatetypelp/give-up.hpp: typedef forGiveUptypelp/nack.hpp:Nacktypelp/caching-policy.hpp:CachingPolicytypelp/field.hpp: a Doxygen comment to defineFieldconcept and a concept checklp/detail/field-decl.hpp: templates and specializations used for declaring fieldslp/fields.hpp: field declaration typedefs

I have no objections for this structure (I'm assuming it would go under src/)

Thanks for approval. Of course it's src/lp/*.hpp|cpp for implementation and tests/unit-tests/lp/*.t.cpp for testing.

Where does the Packet class fit in this directory structure?

Opps I missed that.

Due to Nack API change (#2841 note-31), there's only one Nack-related header:
lp/nack.hpp:Nacktype

In commit:12726d8645f08edc862259b03550abaff6008066, @Alex expressed concern about concepts.hpp being included everywhere.
I neither agree nor disagree with this concern.
Although nack-reason.hpp is gone, the same situation would happens for field.hpp under current design.
If there's a valid reason, I'll change the design.
@Alex, please state the reason why it's harmful to include concepts.hpp everywhere.
Notice that concept checks are header-only and thus does not incur runtime overhead.

Are Nack, NackHeader, and NackReason all in lp/nack.hpp?

Answer to note-12:
I forgot about the other two types. This should be:
lp/nack-header.hpp:NackReasontype andNackHeadertypelp/nack.hpp:Nacktype

Due to CachePolicy design change, the file for this header field is changed to be:
lp/cache-policy.hpp:CachePolicyTypetype andCachePolicytype
