Looking at the doc, and the code, none of those drivers (net/ixgbe, net/atlantic) seem to support this feature. I'll let the maintainers reply on the feasibility. > Which 10G NICs support this option? The documentation from the main repository provides a list of per driver features: https://doc.dpdk.org/guides/nics/overview.html For an already released DPDK, the link becomes https://doc.dpdk.org/guides-/nics/overview.html.
