ixgbe: add support for devlink reload
The E610 adapters contain an embedded chip with firmware which can be
updated using devlink flash. The firmware which runs on this chip is
referred to as the Embedded Management Processor firmware (EMP
firmware).
Activating the new firmware image currently requires that the system be
rebooted. This is not ideal as rebooting the system can cause unwanted
downtime.
The EMP firmware itself can be reloaded by issuing a special update
to the device called an Embedded Management Processor reset (EMP
reset). This reset causes the device to reset and reload the EMP
firmware.
Implement support for devlink reload with the "fw_activate" flag. This
allows user space to request the firmware be activated immediately.
