  Log:
  MFC 1.73:
  
    In em_process_receive_interrupts() store and clear adapter->fmt. This
    make function reenterable. In the runtime the race is masked by
    serializing
    of em_process_receive_interrupts() either by interrupt thread, or by
    polling. The race can be triggered when polling is switched on or off.
