ethtool: add ethtool_rx_flow_spec to flow_rule structure translator
This patch adds a function to translate the ethtool_rx_flow_spec structure to the flow_rule representation. This allows us to reuse code from the driver side given that both flower and ethtool_rx_flow interfaces use the same representation. This patch also includes support for the flow type flags FLOW_EXT, FLOW_MAC_EXT and FLOW_RSS. The ethtool_rx_flow_spec_input wrapper structure is used to convey the rss_context field, that is away from the ethtool_rx_flow_spec structure, and the ethtool_rx_flow_spec structure.
