Subject: [PATCH net-next 00/10] mlxsw: Spectrum-4 preparations

From: Ido Schimmel <idosch@...dia.com>

The Spectrum-4 ASIC will support more than 256 ports, unlike existing
ASICs. As such, various device registers were extended with two
additional bits to encode a 10 bit local port. In some cases, new
(Version 2) registers were introduced.

This patchset prepares mlxsw for Spectrum-4 support by encoding local
port in a 'u16' instead of a 'u8' and by extending the definitions of
the various registers to support the extended local port form.

Amit Cohen (10):
  mlxsw: spectrum: Bump minimum FW version to xx.2010.1006
  mlxsw: reg: Remove unused functions
  mlxsw: item: Add support for local_port field in a split form
  mlxsw: reg: Align existing registers to use extended local_port field
  mlxsw: reg: Increase 'port_num' field in PMTDB register
  mlxsw: reg: Adjust PPCNT register to support local port 255
  mlxsw: Use u16 for local_port field instead of u8
  mlxsw: Add support for more than 256 ports in SBSR register
  mlxsw: Use Switch Flooding Table Register Version 2
  mlxsw: Use Switch Multicast ID Register Version 2
