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

[Hariprasad Kelam]

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.

  Octeontx-pf: Update SGMII mode mapping
  Octeontx2-af: Introduce mode group index
  Octeontx2-pf: ethtool: support multi advertise mode

[net-next 1/3] Octeontx-pf: Update SGMII mode mapping

[Hariprasad Kelam]

Current implementation maps ethtool link modes 10baseT/100baseT/1000baseT
to single firmware mode SGMII. This create a problem for end users who want
to advertise only one speed among them.

This patch addresses the issue by mapping each ethtool link mode
to a corresponding firmware mode also updates new modes supported
by firmware.

[net-next 2/3] Octeontx2-af: Introduce mode group index

[Hariprasad Kelam]

Kernel and firmware communicates via scratch register which is
64 bit in size.

[MODE_ID   PORT    AUTONEG  DUPLEX  SPEED   CMD_ID   OWNERSHIP ]
 63-22     21-14     13      12      11-8    7-2       1-0

The existing MODE_ID bitmap can only support up to 42 modes.
To resolve the issue, the unused port field is modified as below
            uint64_t reserved2:6;
            uint64_t mode_group_idx:2;

'mode_group_idx' categorize the mode ID range to accommodate more modes.

	To specify mode ID range of 0 - 41, this field will be 0.

    	To specify mode ID range of 42 - 83, this field will be 1.

mode ID will be still mentioned as 1 << (0 - 41).  But the mode_group_idx
decides the actual mode range

[net-next 3/3] Octeontx2-pf: ethtool: support multi advertise mode

[Hariprasad Kelam]

Current implementation considers only first advertise
mode and passes the same to firmware to process.
This patch extends code such that user can advertise
multiple modes on the given interface.

Below are high level changes:

1. Remove unnecessary speed/duplex/autoneg validation as its
   already verified as part of "set_link_ksettings"

2. Since scratch csr framework designed to support single mode at a time,
   use "shared firmware data" for multi mode support.
