Summary:
Fixed parser logic to handle non mandatory TLV.
From WIKI:
Each LLDP frame starts with the following mandatory TLVs: Chassis ID, Port ID, and Time-to-Live.
The mandatory TLVs are followed by any number of optional TLVs. The frame ends with a special TLV,
named end of LLDPDU in which both the type and length fields are 0.
