Subject: [RFC PATCH net-next v2 6/6] devlink: add overwrite mode to flash update
A flash image may contain settings or device identifying information.
When performing a flash update, these settings and information may
conflict with contents already in the flash. Devices may handle this
conflict in multiple ways.
Add a new attribute to the devlink command,
DEVLINK_ATTR_FLASH_UPDATE_OVERWRITE_MODE, which specifies how the device
should handle these settings and fields.
DEVLINK_FLASH_UPDATE_OVERWRITE_NOTHING, the default, requests that all
settings and device identifiers within the current flash are kept. That
is, no settings or fields will be overwritten. This is the expected
behavior for most updates, and appears to be how all of the drivers are
implemented today.
DEVLINK_FLASH_UPDATE_OVERWRITE_SETTINGS, requests that the device
overwrite any device settings in the flash section with the settings
from the flash image, but to preserve identifiers such as the MAC
address and serial identifier. This may be useful as a way to restore
a device to known-good settings from a new flash image.
DEVLINK_FLASH_UPDATE_OVERWRITE_EVERYTHING, requests that all content in
the flash image be preserved over content of flash on the device. This
mode requests the device to completely overwrite the flash section,
possibly changing settings and device identifiers. The primary
motivation is to support writing initial device identifiers during
manufacturing. It is not expected to be necessary in normal end-user
flash updates.
For the ice driver, implement support for the overwrite mode by
selecting the associated preservation level to request from firmware.
For all other drivers that support flash update, require that the mode
be DEVLINK_FLASH_UPDATE_OVERWRITE_NOTHING, which is the expected
default.
Update the documentation to explain the overwrite mode attribute.

+ - Description
+ * - ``DEVLINK_FLASH_UPDATE_OVERWRITE_NOTHING``
+ - Do not overwrite any settings or fields in the device flash; only
+ update the associated firmware binaries. This preserves settings
+ stored in the flash, as well as device identifiers. This is the
+ default if no overwrite mode is specified.
+ * - ``DEVLINK_FLASH_UPDATE_OVERWRITE_SETTINGS``
+ - Overwrite device settings stored in the flash with settings from the
+ provided image, but do not overwrite device identifiers such as MAC
+ addresses or serial identifiers. This may be useful to restore a
+ device to default settings from a new image.
+ * - ``DEVLINK_FLASH_UPDATE_OVERWRITE_EVERYTHING``
+ - Overwrite everything in the device flash including settings and
+ device identifiers with the contents from the provided flash image.
+ Unless the provided image has been customized for this device, it
+ will result in clearing the identifying information in the device
+ flash. This mode is primarily intended for device manufacturers
+ performing initial device programming, and is not expected to be
+ necessary when performing regular flash updates.
