Jiri Pirko says: ==================== mlxsw: Support firmware flash Add support for device firmware flash on mlxsw spectrum. The firmware files are expected to be in the Mellanox Firmware Archive version 2 (MFA2) format. The firmware flash is triggered on driver initialization time if the device firmware version does not meet the minimum firmware version supported by the driver. Currently, to activate the newly flashed firmware, the user needs to reboot his system. The first patch introduces the mlxfw module, which implements common logic needed for the firmware flash process on Mellanox products, such as the MFA2 format parsing and the firmware flash state machine logic. As the module implements common logic which will be needed by various different Mellanox drivers, it defines a set of callbacks needed to interact with the specific device. Patches 1-5 implement the needed mlxfw callbacks in the mlxsw spectrum driver. Patches 6 and 7 add boot-time firmware upgrade on the mlxsw spectrum driver. Patch 8 adds a fix needed for new firmware versions. ==================== Signed-off-by:
