Log:
  Mark the ENA driver as epoch ready
  
  Recent changes to the epoch requires driver to notify that they knows
  epoch in order to prevent input packet function to enter epoch each
  time the packet is received.
  
  ENA is using NET_TASK for handling Rx, so it's entering epoch
  automatically whenever this task is being executed.
