[ Upstream commit e42b7e9cefca9dd008cbafffca97285cf264f72d ]
Fix display of parameters "Configured FEC encodings:" and "Advertised FEC modes:" in ethtool. Implemented by setting proper FEC bits in “advertising” bitmask of link_modes struct and “fec” bitmask in ethtool_fecparam struct. Without this patch wrong FEC settings can be shown.
