Symmetric hash function can be configured:
* Set symmetric hash enable per port.
* Set symmetric hash enable per pctype (packet classification type).
* Set the swap configurations.
Commands are implemented for 'rx_classification_filter_ctl'
to support above operations which can be called in applications.
Also 'check_command_supported' is also implemented to check if
a specific capability(command) is supported or not.
