63Flash Update
64============
65
66The ``sfc`` driver implements support for flash update using the
67``devlink-flash`` interface. It supports updating the device flash using a
68combined flash image ("bundle") that contains multiple components (on ef10,
69typically ``fw.mgmt``, ``fw.app``, ``fw.exprom`` and ``fw.uefi``).
70
71The driver does not support any overwrite mask flags.
