About 70% of the chips with revision RT5390R initialize incorrectly, using

This chipset differs from RT5390 and RT5390F by its support of hardware

differently, by disabling software features and previously selected
antenna.
This changeset does just that, and makes all RT5390R work properly.

ath9k: fix TX power reporting on AR9003 chips
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.

2) network_tsf - firmware's TSF value at the time the beacon or probe

Both are needed while associating by firmware.

1) We should pass "timestamp" to cfg80211_inform_bss(), but currently

2) Rename "network_tsf" to "fw_tsf"

There are connection stalls or very poor throughputs with rt2800

failed BAR frames later instead of tearing down aggr"[1][2].
Since rt2800 hardware is not able to correctly report the tx status of
BAR frames, this patch removes as workaround the existing error handling
on AP side, which lets mac80211 send a BAR when an AMPDU subframe fails.
As a result, most wifi clients (aside from Intel STAs on Windows)
instead will timeout now the reorder buffer and request the lost frame
again.
The correct solution would be, to tear down BA session on AP side.
This patch was born on the basis of "[RFT] rt2x00: Tear down BA
session on QoS frame failure"[3].
