Hi Linux Ethernet Team,

We explored Ethtool's "10000base_CR" PMD PHY type
and we think it might be just a wrong name.

Why we called 10000Base_CR, a confusing name?
Because it fails all below 4 major highlights of a "typical base-CR"
    1. Every other Base-CR is an IEEE defined PMD specs
    2. All Base-CR have AN LT (Auto-Negotiation & Link Training)
    3. Almost all CR have FEC mandatory
    4. IEEE CR is a very close sibling of IEEE KR, the complex ones

There is NO IEEE 802.3 or ANY other standard spec to
support 10000base-CR and the industry fully adopted
SFF-8431 Appendix-E Direct Attach cable as 10G-SFI-DA.

We feel 10000Base_CR must be renamed to 10000_SFI_DA.
    SFI: SFP+ high speed serial electrical interface
    DA: Direct Attach cable media

Need your inputs for the next step here. Should we,
(a) Submit a patch to rename all instance of 10000baseCR
OR
(b) Create a new enum for SFI_DA and map it to 10000baseCR?

We prefer option-(a) since it completely resolves the confusion
and gives a technically correct name.

- Thank you,
