I think it is necessary to check which type of packets are stamped by nic. For I350 (igb), it only support HWTSTAMP_FILTER_NONE and HWTSTAMP_FILTER_ALL of outgoing packets.For 82599EB(ixgbe), we can check more. I add a new member of hwtstamp_config to judge the ioctl request is read or write, we can specify the rw in the userspace using hwstamp_ctl application to get the time stamped info. -- Best Regards, Dong Zhu -- To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majord...@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
