TODO:
|
|
- Find out lots more values :-)
|
|
- Find out set authentication mechanism, offer verification option
|
|
- Support for other 3com devices that use the same protocol
|
|
- Do any devices use TCP or different ports?
|
|
- Sanity checks for tlv_length depending on tlv_type
|
|
- Search and fix XXX comments in the code
|
|
- Proper descriptions in hf_ fields
