The device raises error indications when it thinks there is a bug in the
driver and it can't recover it (while it raises exception when a bug is
detected in the device).

The current list of of errors was a bit dated.

This patch cleans up the list of errors and the associated message. It
is also the right time to clean up the way the error indications are
handled. Replace the switch..case with a clean loop over an array.

Until now, the exception received from the chip was only displayed if

In some circumstances, Tx traffic is sent without associated station but
the station exists when the Tx status is received. Beside that, the
driver keep a counter associated to each station. So, in this case, the
counter is not incremented, but is decremented. In this case a warning
"inconsistent notification" appears:

It has been reported that trying to send small packets of data could
produce a "inconsistent notification" warning.

It seems that in some circumstances, the number of frame queued in the
driver could greatly increase and exceed UCHAR_MAX. So the field
"buffered" from struct sta_priv can overflow.

Just increase the size of "bueffered" to fix the problem.

wfx_suspend_resume_mc() is called when the device is about to sent a
DTIM. This is the right moment to enqueue Content After DTIM Beacon
(CAB).

However, wfx_suspend_resume_mc() is also called when the DTIM period
ends. Until now, this event did also trig CAB.

Note this issue did not have too much impact since when a CAB is sent
outside of DTIM window, an error is reported by the firmware and
mac80211 retries to send the data.

When multiple virtual interfaces (on different channels) are in use, the
device ask to activate Power Save on station interfaces. The device
developers recommends to use legacy PS-Poll in this case since it is the
mode that disturb the less the other interface. However, some AP start
to not answer anymore to PS-Poll. The device is able to detect this case
and return a special warning in this case.

So, this commit catch the warning and force usage of FastPS in this
case.

In order to confuse the less possible the other interface a small FastPS
period is used (30ms).

This happens because the variable fw_fallback_config is built into the
