sfc devlink support

This document describes the devlink features implemented by the sfc device driver for the ef10 and ef100 devices.

Info versions

The sfc driver reports the following versions

devlink info versions implemented

Name	Type	描述
fw.bundle_id	stored	Version of the firmware "bundle" image that was last used to update multiple components.
fw.mgmt.suc	running	For boards where the management function is split between multiple control units, this is the SUC control unit's firmware version.
fw.mgmt.cmc	running	For boards where the management function is split between multiple control units, this is the CMC control unit's firmware version.
fpga.rev	running	FPGA design revision.
fpga.app	running	Datapath programmable logic version.
fw.app	running	Datapath software/microcode/firmware version.
coproc.boot	running	SmartNIC application co-processor (APU) first stage boot loader version.
coproc.uboot	running	SmartNIC application co-processor (APU) co-operating system loader version.
coproc.main	running	SmartNIC application co-processor (APU) main operating system version.
coproc.recovery	running	SmartNIC application co-processor (APU) recovery operating system version.
fw.exprom	running	Expansion ROM version. For boards where the expansion ROM is split between multiple images (e.g. PXE and UEFI), this is the specifically the PXE boot ROM version.
fw.uefi	running	UEFI driver version (No UNDI support).

Flash Update

The sfc driver implements support for flash update using the devlink-flash interface. It supports updating the device flash using a combined flash image ("bundle") that contains multiple components (on ef10, typically fw.mgmt, fw.app, fw.exprom and fw.uefi).

The driver does not support any overwrite mask flags.
