Linux Kernel Upstream Release Notes v6.5

VXLAN technology provides scalability and security challenges solutions. It requires extension of the traditional stateless offloads to avoid performance drop. ConnectX®-3 Pro adapter cards offer stateless offloads for a VXLAN packet, similar to the ones offered to non-encapsulated packets. VXLAN protocol encapsulates its packets using outer UDP header.

ConnectX®-3 Pro supports offloading of tasks related to VXLAN packet processing, such as TCP header checksum and VMQ (i.e.: directing incoming VXLAN packets to the appropriate VM queue).

Due to hardware limitation, on a dual-port adapter, VXLAN offload service cannot be provided simultaneously for both Ethernet ports if they are not using the same UDP port for VXLAN tunneling.
