====================
Mellanox 100G mlx5 ethtool ntuple steering

This series adds Ethernet ethtool ntuple steering 'ethtool -N|U' and exposes two more
counter sets to Ethtool statistics, RDMA vport and global flow control statistics.

We start from three refactoring patches of the flow steering infrastructure
    - mlx5_add_flow_rule will now receive mlx5 flow spec to simplify and reduce
      number of parameters
    - All low level steering objects are now wrapped in mlx5_flow_steering structure
      for better encapsulation
    - Flow steering object will now be removed properly and generically rather than
      traversing on a well-known steering tree objects

Patch#4 adds the infrastructure and the data structures needed for the ethtool ntuple
steering, all implemented in a new file 'en_fs_ethtool.c'.  Add the support for set_rxnfc
ethtool callback to add/remove/replace a flow spec of ethter type L2.

Patch#5 adds the support for L3/L4 flow specs and a higher priority in favor for L3/L4
rules when interleaving with L2 rules.

Patch#6 adds the support for get_rxnfc ethtool callback.

Patch#7,8 adds RDMA vport and global flow control statistics.
