Victor Boivie	58fa1bac03	dcsctp: Enforce variable length TLV minimum length ... The length field was validated to not be too big, or to have too much padding, but it could be smaller than the fixed size of the chunk, which isn't correct. Now it's enforced to be at minimum the size of the fixed size header.

Victor Boivie	3dffa81541	dcsctp: Add TLV trait ... Various entities in SCTP are padded data blocks, with a type and length field at fixed offsets, all stored in a 4-byte header. This is called the Type-Length-Value format, or TLV for short. See e.g. https://tools.ietf.org/html/rfc4960#section-3.2 and https://tools.ietf.org/html/rfc4960#section-3.2.1 This templated class, which is used as a trait[1], is configurable - a struct passed in as template parameter.
