> Gianfar interrupt handler uses IEVENT_ERR_MASK to check and handle errors.
> Babbling RX error (IEVENT_BABR) should be included in IEVENT_ERROR_MASK.
> Otherwise if BABR is raised, it never gets handled nor cleared, and an
> interrupt storm results. This has been observed to happen on sending a
> burst of ethernet frames to a gianfar based board.
