It has no autonegotiation, no link training, and no mandatory FEC. The industry standard for this media type is SFF-8431 Appendix-E Direct Attach cable, also known as 10G_SFI_DA. This change follows the conversation from netdev mail thread with subject: "the confusing 10000base_CR. Shouldn't it be 10000_SFI_DA?"
