isoc_bei_interval is used to balance how often completed isochronous events cause interrupts. If interval is too large then the event ring may fill up before the completed isoc TRBs are handled. isoc_bei_interval is tuned based on how full the event ring is. isoc_bei_interval variable needs to be per interrupter as with several interrupters each one has its own event ring. move isoc_bei_interval variable to the interrupter structure. if a secondary interrupter does not care about this feature then keep isoc_bei_interval 0.
