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.
