Before the “json” option was instroduced, all options were listed. Currently, only the last option is listed. This commit fixes this bug. Options are represented as array. Before: $ ethtool -m sfp-wan ... Option values : 0x00 0x32 Option : RATE_SELECT implemented ... $ ethtool --json -m sfp-wan [ { ... "option_values": [ 0,50 ], "option": "RATE_SELECT implemented", ... } ] After: $ ethtool -m sfp-lan ... Option values : 0x00 0x32 Option : RX_LOS implemented Option : TX_DISABLE implemented Option : RATE_SELECT implemented ... $ ethtool --json -m sfp-lan [ { .. "option_values": [ 0,50 ], "option": [ "RX_LOS implemented","TX_DISABLE implemented","RATE_SELECT implemented" ], } ] ..
