I'll have to find the errata and see if any of the details can help me out. NAPI depends on being able to mask the interrupt. Is an old style mode of handling the packets directly in tg3_interrupt acceptable these days? i.e. leave the interrupt blocked while handling packets. My hope is it would be very efficient - zero MMIO reads. Maybe there is another way to throttle RX packets? thanks, grant - : send the line "unsubscribe linux-net" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
