This patch series aims to use new vTcam and Counter API
provided by latest fw version. The advantage of using
this API is the following:

- provides a way to have a rule with desired Tcam size (improves
  Tcam memory utilization).
- batch support for acl counters gathering (improves performance)
- gives more control over HW ACL engine (actions/matches/bindings)
  to be able to support more features in the future driver
  versions

Note: the feature set left the same as was before this patch.
