Error: altera_eth_10gbaser_phy.xcvr_native_a10_0: The current value "disabled" (0) for parameter "Enable TX scrambler (10GBASE-R/Interlaken)" (enh_tx_scram_enable) is invalid. Possible valid values are: "enabled" (1). The parameter value is invalid under these current parameter settings: "device_family" (device_family)="" (Cyclone 10 GX) && "Enhanced PCS / PMA interface width" (enh_pcs_pma_width)="32" && "FPGA fabric / Enhanced PCS interface width" (enh_pld_pcs_width)="66" && "Transceiver configuration rules" (protocol_mode)="10GBASE-R" (teng_baser_mode). Rule(s): hssi_10g_tx_pcs_scrm_bypass.

thanks,

Carl
