Add the ability to flash the modules' firmware by implementing the interface between the user space and the kernel. Example from a succeeding implementation: # ethtool --flash-module-firmware swp40 file test.bin Transceiver module firmware flashing started for device swp40 Transceiver module firmware flashing in progress for device swp40 Progress: 99% Transceiver module firmware flashing completed for device swp40 In addition, add infrastructure that allows modules to set socket-specific private data. This ensures that when a socket is closed from user space during the flashing process, the right socket halts sending notifications to user space until the work item is completed.
