Detailed Description

trace sink for wifi device that mimics madwifi's athstats tool.

The AthstatsWifiTraceSink class is a trace sink to be connected to several of the traces available within a wifi device. The purpose of AthstatsWifiTraceSink is to mimic the behavior of the athstats tool distributed wih the madwifi driver. In particular, the reproduced behavior is that obtained when executing athstats without parameters: a report written in text format is produced every fixed interval, based on the events observed by the wifi device.

Differences with the "real" athstats:

AthstatsWifiTraceSink is expected to write its output to a file (not to stdout).

only a subset of the metrics supported by athstats is supported by AthstatsWifiTraceSink

AthstatsWifiTraceSink does never produce a cumulative report.
