Use the pldmfw library to implement device flash update for the Intel ixgbe networking device driver specifically for E610 devices. This support uses the devlink flash update interface. Using the pldmfw library, the provided firmware file will be scanned for the three major components, "fw.undi" for the Option ROM, "fw.mgmt" for the main NVM module containing the primary device firmware, and "fw.netlist" containing the netlist module. The flash is separated into two banks, the active bank containing the running firmware, and the inactive bank which we use for update. Each module is updated in a staged process. First, the inactive bank is erased, preparing the device for update. Second, the contents of the component are copied to the inactive portion of the flash. After all components are updated, the driver signals the device to switch the active bank during the next EMP reset. With this implementation, basic flash update for the E610 hardware is supported.
