Subject: [PATCH net 0/6] Ocelot VCAP fixes

This series fixes issues found while running
tools/testing/selftests/net/forwarding/tc_actions.sh on the ocelot
switch:

- NULL pointer dereference when failing to offload a filter
- NULL pointer dereference after deleting a trap
- filters still having effect after being deleted
- dropped packets still being seen by software
- statistics counters showing double the amount of hits
- statistics counters showing inexistent hits
- invalid configurations not rejected

Vladimir Oltean (6):
  net: mscc: ocelot: don't use list_empty() on non-initialized list
    element
  net: mscc: ocelot: avoid use after free with deleted tc-trap rules
  net: mscc: ocelot: fix last VCAP IS1/IS2 filter persisting in hardware
    when deleted
  net: mscc: ocelot: fix VCAP IS2 filters matching on both lookups
  net: mscc: ocelot: restrict tc-trap actions to VCAP IS2 lookup 0
  net: mscc: ocelot: avoid corrupting hardware counters when moving VCAP
    filters
