Subject[PATCH net-next 0/5] net: mvpp2: add debugfs interface
Date
The PPv2 Header Parser and Classifier are not straightforward to debug,
having easy access to some of the many lookup tables configuration is
helpful during development and debug.

This series adds a basic debugfs interface, allowing to read data from
the Header Parser and some of the Classifier tables.

For now, the interface is read-only, and contains only some basic info.

This was actually used during RSS development, and might be useful to
troubleshoot some issues we might find.

The first patch of the series converts the mvpp2 files to SPDX, which
eases adding the new debugfs dedicated file.

The second patch adds the interface, and exposes basic Header Parser data.

The 3rd patch adds a hit counter for the Header Parser TCAM.

The 4th patch exposes classifier info.

The 5th patch adds some hit counters for some of the classifier engines.
