ethtool: Veto some operations during firmware flashing process
Some operations cannot be performed during the firmware flashing
process.
For example:
- Port must be down during the whole flashing process to avoid packet loss
while committing reset for example.
- Writing to EEPROM interrupts the flashing process, so operations like
ethtool dump, module reset, get and set power mode should be vetoed.
- Split port firmware flashing should be vetoed.
In order to veto those scenarios, add a flag in 'struct net_device' that
indicates when a firmware flash is taking place on the module and use it
to prevent interruptions during the process.
