For some reason the MAC timing is a bit off when waiting for ACKs, so add
some extra delay to the ACK timeout values. Significantly reduces the
number of retransmissions in my tests.
Also disable the 2.4 GHz ACK timeout workaround in half/quarter mode, it
is not required there.

AR9462 uses modified version of 3-Wire hw scheme for btcoex.
MCI itself is not a separate hw scheme but it aids to manage
multiple bt profiles. In ar9462, bt priority traffic is identified
by the number of bt profile types instead of gpio. So that this
patch removes MCI hw scheme.

The current code unconditionally reads the target
power values for all modes from the EEPROM. However
In 'ar9003_hw_set_power_per_rate_table' the regulatory
caps are applied only on a mode specific subset of the
power values.

The reported TX power level is calculated from the
maximum of the power values. Because some of these
values are uncapped in certain cases, the reported
TX power will be wrong.

On the older chipset, we don't have such problems
because only the mode specific subset of the power
levels are retrieved from the EEPROM on those. Do
the same for the AR9003 chips to fix the issue.

This based on an idea posted by Stanislaw Gruszka,
though I accept full blame for the implementation!

This has been tested with ath9k.

The idea is to let users scan on the current operating
channel without interrupting normal traffic more than
absolutely necessary (changing power level might reset
some hardware, for instance).

Having cmd[], meta[] and skbs[] as separate arrays
in the TX queue structure is cache inefficient as
we need the data for a given entry together.

To improve this, create an array with these three
members (allocate meta as part of that struct) so
we have the data we need together located together
improving cache footprint.

The downside is that we need to allocate a lot of
memory in one chunk, about 10KiB (on 64-bit) which
isn't very efficient.
