ethtool: link 10000baseCR to SFF-8431, Appendix-E SFP+ DA
Add comment to clarify the physical media 10000baseCR follows.
10000baseCR does not correspond to any IEEE 802.3 *base-CR PMD.
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.
