net/mlx5: Prevent high-rate FW commands from populating all slots
Certain connection-based device-offload protocols (like TLS) use per-connection HW objects to track the state, maintain the context, and perform the offload properly. Some of these objects are created, modified, and destroyed via FW commands. Under high connection rate, this type of FW commands might continuously populate all slots of the FW command interface and throttle it, while starving other critical control FW commands. Limit these throttle commands to using only up to a portion (half) of the FW command interface slots. FW commands maximal rate is not hit, and the same high rate is still reached when applying this limitation.
