[PATCH net-next V2 0/3] net: Add 1600Gbps (1.6T) link mode support

[Tariq Toukan <tariqt@nvidia.com>]

This series by Yael adds 1600Gbps (1.6T) link mode support.
See detailed description by Yael below.

Tariq


This series adds 1600Gbps (1.6T) link mode support end-to-end.
- Introduces 1600Gbps ethtool link modes based on 200Gbps-per-lane
  signaling from IEEE 802.3dj, including KR8/CR8/DR8/DR8-2 PMDs.
- Wires up mlx5e to advertise and handle the new modes (8 lanes x
  200Gbps).
- Extends bonding 802.3ad to accept and operate with 1600Gbps links.

User-visible effects:
- ethtool will report and advertise 1600Gbps modes and PMDs where
  supported.
- mlx5 devices capable of 8x200Gbps lanes will expose 1600Gbps.
- LACP (bonding 3ad) will accept and utilize 1600Gbps partner links.

Compatibility:
- UAPI additions only; existing users are unaffected.
- The new link modes/PMDs are additive and aligned with IEEE 802.3dj
  200G/lane definitions.

Testing:
- Verified ethtool reporting/advertisement and 1600Gbps link bring-up
  using simulated mlx5 hardware.
- No regressions observed at lower speeds.
