ethtool: Add ability to flash transceiver modules' firmware
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.
