ConnectX-3 Pro VPI/EN Receive VXLAN Offloading


With assumption that all Mellanox ConnectX-3 Pro EN features are covered by Mellanox ConnectX-3 Pro VPI, I’m interested on Mellanox ConnectX-3 Pro EN vs Intel XL710 comparison on . I’m focusing on the different of Overlay Networks on page 2 where states that Intel XL710 only do VXLAN offloading only on transmit (Tx). If I refer to “ethtool -k” result on for ConnectX-3 Pro EN and Figure 11 on (page 15) for Intel XL710, I cannot see any different related to Receive (Rx) VXLAN offloading. I’m looking the status or configuration capture which show that different. Is ConnectX-3 Pro (VPI and/or EN) really have receive VXLAN offloading capability?

Best regards,

In order to validate receive VXLAN offload, you can configure the system by using ‘ethtool’ and settingg rx-checksumming and GRO on receive side, run the traffic and observe that receive packet size is bigger than MTU using wireshark/tcpdump on receiver side.
