An hwconfig env "fsl_10gkr_copper" is + introduced to indicate a XFI port will use copper cable, and U-boot + will fixup the dtb accordingly. + It's used as: fsl_10gkr_copper:<10g_mac_name> + The <10g_mac_name> can be fm1_10g1, fm1_10g2, fm1_10g3, fm1_10g4, they + do not have to be coexist in hwconfig.
