Unconditionally configure HT rate support to the FW on all ACs
when starting the AP.
When 11n support is disabled by usermode (hostapd), each STA joining
the AP will appear as a non-HT STA. This will stop us from accidentally
transmitting using MCS rates.

A recently added feature to the firmware enables the driver to retrieve
firmware logs via the host bus (SDIO or SPI).
There are two modes of operation:
1. On-demand: The FW collects its log in an internal ring buffer. This
buffer can later be read, for example, upon recovery.
2. Continuous: The FW pushes the FW logs as special packets in the RX
path.
Reading the internal ring buffer does not involve the FW. Thus, as long
as the HW is not in ELP, it should be possible to read the logs, even if
the FW crashes.
A sysfs binary file named "fwlog" was added to support this feature,
letting a monitor process read the FW messages. The log is transferred
from the FW only when available, so the reading process might block.

Use a different value for DFS dwell time when performing a scheduled
scan. Previously we were using the same value as for normal passive
scans. This adds some flexibility between these two different types
of passive scan.
For now we use 150 TUs for DFS channel dwell time. This may need to
be fine-tuned in the future.

In AP mode we register for the MAX_TX_RETRY and INACTIVE_STA events.
Both are reported to the upper layers as a TX failure in the offending

In STA mode we register only for the MAX_TX_RETRY event. A TX failure is
interpreted as a loss of connection.
Support for IEEE80211_HW_REPORTS_TX_ACK_STATUS has been removed to avoid
the inherent race condition of a mac80211 TX failure counter in addition
to the FW counter.

The passive scan channel dwell time currently used is 30-60TU. A typical
beacon interval for AP's is 100TU. This leads to a ~30% worst-case probability
of finding an AP via passive scanning.
For 5GHz bands for DFS frequencies passive scanning is the only scanning
option. Hence for these, the probability of finding an AP is very low.
To fix this, increase the passive channel scan dwell times (also the early
leave value, as 5GHz channels are still typically very silent.) Use a value
of 100TU, because that covers most typical AP configurations.
Based on testing the probability of finding an AP (100TU beacon interval) on
a single scan round are as follows (based on 100 iterations):
dwell min/max (TU) | probability
---------------------+------------
30/60 | 35%
60/60 | 56%
80/80 | 77%
100/100 | 100%
Total scan times now and after the change:
Region | Before (s) | After (s)
-------+------------+----------
00 | 0.77 | 1.48
FI | 0.95 | 2.01
US | 0.91 | 1.76
