> I think you're right. To my opinion, this if is added to avoid the race condition. So, it should be " dev->data->dev_conf.intr_conf.lsc == 0". It means if the interrupts are not enabled, we'd update the link when starting, if not we can leave it the interrupt handler.

Tim, please could you send an appropriate patch?
The procedure is described in http://dpdk.org/dev#send

Could you also check if other PMDs have the same bug?
Thanks
