The Buffalo device WZR-HP-G450H uses the index 3 for TX gain,
which is set to the high_power table currently. Later variants
of the router use the same index, but instead refer to the
low_ob_db gain table. This is not handled in the driver since
there is no way to distinguish board revisions and the high_power
table is used (incorrectly) for the newer variants.
By default, devices based on AR9300 using the TX gain index 3 have
to use the high_power table. To make sure that WZR-HP-G450H is not
broken when the high_power table is updated, use a separate array
based on information obtained from the platform data.
The current situation where only the original variant of WZR-HP-G450H
works properly stays unchanged.

Rewrite the search cycle state machine to use a more data

limitations and next columns to search are reprsented in

several major fixes:
1. Prevent going back to a specific Tx column in a search
cycle if it was already explored.
2. Avoid switching to a Tx column that doesn't have any chance
if it performs perfectly to beat the current throughput we're
getting.
These issues were degrading throughput as they were causing

Expected TPT table was updated only when switching to a new
modulation. This is wrong as toggling aggregation changes
the expected TPT signficantly.
This leads to scenarios where turning aggregation on after

This occurred because the TPT of the SISO mode was being
estimated based on aggregation while the MIMO one wasn't.
