Introducing the following objects:
mlx5_flow_root_namespace: represent the root of specific flow table
type tree(e.g NIC receive, FDB, etc..)
mlx5_flow_group: define the mask of the flow specification.
fs_fte(flow steering flow table entry): defines the value of the
flow specification.
The following describes the relationships between the tree objects:
root_namespace --> priorities -->namespaces -->
priorities -->flow-tables --> flow-groups -->
flow-entries --> destinations
When we create new object(flow table/flow group/flow table entry), we
call to the FW command and then we add the related sw object to the tree.
When we destroy object, e.g. call to mlx5_destroy_flow_table, we use
the tree node destructor for destroying the FW object and remove the
node from the tree.
