Module ie 

IEEE 802.11 Information Elements (IEs).

Information elements are TLV (Tag-Length-Value) structures appended to management frame bodies (beacons, probe requests/responses, etc.).

Each IE has a 1-byte ID, 1-byte length, and variable-length data. This module provides a generic Dot11Elt for arbitrary IEs, plus specialized parsers for common IEs (SSID, Rates, RSN, HT, VHT, etc.).
