These modes were added to ethtool.h in 5711a98221443 ("net: ethtool: add support
for 1000BaseX and missing 10G link modes") back in 2016.

Only setting CR mode for 10G, similar to how 25/40/50/100G modes are set up.

Tested using SFN5122F-R7 (with 2 SFP+ ports) and a 1000BASE-BX10 SFP module.

Did you test with a Copper SFP modules?

I have tested it with a copper SFP PHY at 1G and that works fine.

Meaning ethtool returns 1000BaseT_FULL? Does the SFP also support
10/100? Does ethtool list 10BaseT_Half, 10BaseT_Full, etc.
