Subject: [patch net-next v2 0/8] mlxsw: Support firmware flash

From: Jiri Pirko <jiri@...lanox.com>

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.
