Jakub Kicinski 76726ccb7f devlink: add flash update command ... Add devlink flash update command. Advanced NICs have firmware stored in flash and often cryptographically secured. Updating that flash is handled by management firmware. Ethtool has a flash update command which served us well, however, it has two shortcomings: - it takes rtnl_lock unnecessarily - really flash update has nothing to do with networking, so using a networking device as a handle is suboptimal, which leads us to the second one: - it requires a functioning netdev - in case device enters an error state and can't spawn a netdev (e.g. communication with the device fails) there is no netdev to use as a handle for flashing. Devlink already has the ability to report the firmware versions, now with the ability to update the firmware/flash we will be able to recover devices in bad state. To enable updates of sub-components of the FW allow passing component name. This name should correspond to one of the versions reported in devlink info. v1: - replace target id with component name (Jiri).
