Suanming Mou d1559d66ed net/mlx5: add table management 
Flow table is a group of flows with the same matching criteria
and the same actions defined for them. The table defines rules
that have the same matching fields but with different matching
values. For example, matching on 5 tuple, the table will be
(IPv4 source + IPv4 dest + s_port + d_port + next_proto)
while the values for each rule will be different.

The templates' relevant matching criteria and action instances
will be created in the table creation and saved in the table.
As table attributes indicate the supported flow number, the flow
memory will also be allocated at the same time.

This commit adds the table management functions.
