Small update, found while verifying against the standard.
Thanks
Jörg
The results of a boring train ride:
- Decode some IEs sent by other traveller's devices
+ IBSS ATIM window
+ TPC report
+ Old ERP IE (802.11g D4.0)
- Tiny whitespace fix
- Add Unit 'TUs' to beacon interval.
v2: TPC: Link margin element is not used in beacons
In case this project requires a sob:
