Subject: [PATCH net-next 8/8] mlxsw: spectrum: Extend to support Spectrum-4 ASIC
From: Amit Cohen <amcohen@...dia.com>
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.
