Subject: [net-next 0/3] Octeontx2-pf: extend link modes support

This series of patches adds multi advertise mode support along with
other improvements in link mode management code flow.

Patch1: Currently all SGMII modes 10/100/1000baseT are mapped with
        single firmware mode. This patch updates these link modes
        with corresponding firmware modes.

Patch2: Due to limitation in current kernel <-> firmware communication,
        link modes are divided into multiple groups, and identified
        with their group index.

Patch3: Adds support for multi advertise mode.

Hariprasad Kelam (3):
  Octeontx-pf: Update SGMII mode mapping
  Octeontx2-af: Introduce mode group index
  Octeontx2-pf: ethtool: support multi advertise mode
