qca6174 WLAN.RM.2.0-00073 firmware uses full rx
reordering offload and delivers Rx via a new HTT
event. The event however is incorrectly generated
in firmware and becomes overly long (with trailing
garbage). This was hitting defined CE buffer limit
that was programmed to the device and caused
device to crash upon busier Rx traffic.

Increasing the CE buffer limit for HTT Rx pipe to
2KBytes seems to be enough to workaround this
problem.

iwlwifi: mvm: add trigger for firmware dump upon statistics

It can be very useful to monitor the statistics and trigger
a firmware dump when a certain value hits a certain offset.
Since the statistics are huge, add a generic trigger. When
the DWORD at offset X reaches value Y.

Since there is another trigger before this one I can't add
right now because of a dependency on mac80211, add a
reserved entry to keep the enum in place.

hard to stop the recording on time and get meaningful

In order to solve this, I add here an infrastucture
of triggers. The user will supply a list of triggers
that will start / stop the recording. We have two types
of triggers: start and stop. Start triggers can start a
specific configuration. The stop triggers will be able to
kick the collection of the data with the currently running
configuration. These triggers are given to the driver by
the .ucode file - just like the configuration.
