[PATCH net-next 0/5] Improve locking in the VCAP API

[Steen Hegelund <steen.hegelund@microchip.com>]

This improves the VCAP cache and the VCAP rule list protection against
access from different sources.

The VCAP Admin lock protects the list of rules for the VCAP instance as
well as the cache used for encoding and decoding rules.

This series provides dedicated functions for accessing rule statistics,
decoding rule content, verifying if a rule exists and getting a rule with
the lock held, as well as ensuring the use of the lock when the list of
rules or the cache is accessed.

Steen Hegelund (5):
  net: microchip: sparx5: Add support for rule count by cookie
  net: microchip: sparx5: Add support to check for existing VCAP rule id
  net: microchip: sparx5: Add VCAP admin locking in debugFS
