The rohc_stats tool outputs statistics in CSV format with the following tab−separated fields:
* keyword ’STAT’
* packet number
* context mode (numeric ID)
* context mode (string, no whitespace)
* context state (numeric ID)
* context state (string, no whitespace)
* packet type (numeric ID)
* packet type (string, no whitespace)
* uncompressed packet size (bytes)
* uncompressed header size (bytes)
* compressed packet size (bytes)
* compressed header size (bytes)
