Subject: mlxsw: spectrum: Extend to support Spectrum-4 ASIC
Patch-mainline: v5.17-rc1
Git-commit: 4735402173e6eed18d7e04cfc4bc358d8b2965db
References: jsc#PED-1549
Extend existing driver for Spectrum, Spectrum-2 and Spectrum-3 ASICs
to support Spectrum-4 ASIC as well.
Currently there is no released firmware version for Spectrum-4, so the
driver is not enforcing a minimum version.
