Longer answer: The transmit checksum API interface in DPDK expects that any encapsulation headers are done as transmit offloads. There is no API for devices to report MPLS offload, and there is no driver that supports it. If you have the hardware support, would love to see this as a future enhancement. --=20 You are receiving this mail because: You are the assignee for the bug.=
