This series add rss support for HINIC driver and implement the ethtool
interface related to rss parameter configuration. user can use ethtool
configure rss parameters or show rss parameters.
Xue Chaojing (3):
hinic: add rss support
hinic: move ethtool code into hinic_ethtool
hinic: add support for rss parameters with ethtool
