net: ethtool: Add support for 1600Gbps speed
Add support for 1600Gbps link modes based on 200Gbps per lane [1].
This includes the adopted IEEE 802.3dj copper and optical PMDs that use
200G/lane signaling [2].
Add the following PMD types:
- KR8 (backplane)
- CR8 (copper cable)
- DR8 (SMF 500m)
- DR8-2 (SMF 2km)
These modes are defined in the 802.3dj specifications.
