TODO:

organization specific TLV e.g. ProfiNet

(see LLDPDUGenericOrganisationSpecific for a starting point)
Ignore everything after EndofLLDPDUTLV

NOTES:

you can find the layer configuration options at the end of this file
default configuration enforces standard conform:
- frame structure
  
  (ChassisIDTLV/PortIDTLV/TimeToLiveTLV/…)
- multiplicity of TLVs (if given by the standard)
- min sizes of strings used by the TLVs
