Hi Ueimor, 
My observation is there is mix-up of names in current ioctl implementation where ethtool_get_rxfh() is called for ETHTOOL_GRSSH command. Since this implementation is for ETHTOOL_GRSSH ioctl, we are using RSS instead of RXFH as Jakub suggested earlier. Why do you think it should be ETHOOL_GRXFH ?

https://elixir.bootlin.com/linux/latest/source/net/ethtool/ioctl.c#L2916

	case ETHTOOL_GRXFH:
		rc = ethtool_get_rxnfc(dev, ethcmd, useraddr);

	case ETHTOOL_GRSSH:
		rc = ethtool_get_rxfh(dev, useraddr);
