Gal Pressman b62869a81a ethtool: rss: Fix hfunc and input_xfrm parsing on big endian ... ETHTOOL_A_RSS_HFUNC and ETHTOOL_A_RSS_INPUT_XFRM are NLA_U32 attributes, but ethnl_rss_set() and ethnl_rss_create_doit() parse them with ethnl_update_u8(), which reads a single byte. On little endian this happens to read the least significant byte and works as long as the value fits in a byte. On big endian it reads the most significant byte, so the requested value is parsed incorrectly. The destination fields in struct ethtool_rxfh_param are u8, so the attribute can't be read directly with ethnl_update_u32(). Cap the hfunc policy at U8_MAX so an out of range value is rejected instead of being silently truncated into the u8 field, and add ethnl_update_u8_u32() to read the full u32 and narrow it into the u8 destination.
