Provide additional statistic support to the debugfs.
Current Tx Rate:
The rc_stats file in the debugfs provides the a more detailed
information of individual rates(success, retries, PER etc). But the
current tx rate may not be evidently interpreted from this. This
statistic will provide the current tx rate evidently.
