net/mlx5: Geneve, Manage Geneve TLV options
Use Geneve TLV Options object to manage the flex parser matching
on the 32-bit options data.
When the first flow with a certain class/type values is requested to
be offloaded, create a FW object with FW command (Geneve TLV Options
general object) and start counting the number of flows using this object.
During this time, any request with a different class/type values will
fail to be offloaded.
Once the refcount reaches 0, destroy the TLV options general object,
and can now offload a flow with any class/type parameters.
Geneve TLV Options object is added to core device.
It is currently used to manage Geneve TLV options general
object allocation in FW and its reference counting only.
In the future it will also be used for managing geneve ports
by registering callbacks for ndo_udp_tunnel_add/del.
