I thought it might be easy to get it to work, since it might be just some register that is missing. However I discovered that the e1000 driver uses the legacy transmit descriptor format and therefore the Launch Time feature is not easily available at all in DPDK. Do you see any other options I have to use this feature in DPDK? Are there plans to move to the new Transmit Descriptor Format? Best regards Kilian Holzinger
