ath9k: Fix IQ cal post processing for SoC

Calibration data is not reused for SoC chips, so
call ar9003_hw_tx_iq_cal_post_proc() with the correct
argument. The 'is_reusable' flag is currently used
only for PC-OEM chips, but it makes things clearer to
specify it explicity.

Sujith Manoharan [Thu, 6 Feb 2014 04:52:55 +0000 (10:22 +0530)]
ath9k: Remove ath9k rate control

There is no benefit in retaining the legacy rate control module
in the driver codebase.

It is known to be buggy and has less than optimal performance
in real-world environments compared with minstrel. The only
reason that it was kept when we made the switch to minstrel
as default was that it showed higher throughput numbers in a
clean/ideal environment.

This is no longer the case and minstrel can push ath9k to
the same throughput levels. In TCP, with 3-stream cards, more than
295 Mbps can be obtained in open air, with 2-stream cards,
210 Mbps is easily reached. To test performance issues,
instead of using a broken rate control module, it is better
to use the fixed-rate interface provided by mac80211 anyway.

The ath9k RC has not received any bug fixes in years and is
just bit-rotting away - this patch removes it.
