For the record, netaccel needs to remove any mappings of the hardware during the suspend callback since those mappings are not valid after the suspend has completed. Those hardware mappings (or the mappings appropriate for the new machine) are restored on resume as a result of the standard netfront/netback connection being re-established. If the suspend is cancelled, the netfront/netback connection stays in place but the hardware mappings need to be re-established which is why the suspend_cancel callback is used.
