Changes and New Features



IPv6 support

[Beta] Added support for the latest Internet Protocol version IPv6.

Note: Support for IPv6 at beta level involves some limitations that can be viewed under Known Issues.


Added support for TLS v1.2: 256 bits; TLS v1.3: 128 bits; and TLS v1.3: 256 bits.

C++11 Standard Support

Product source code is migrated to C++11 standard requirements.


We recommend using libnl3 as it is the latest version and includes fixes related to libnl1.


Bonding Active-Backup not supported.
RoCE LAG is a feature meant for mimicking Ethernet bonding for IB devices and is available for dual-port cards only. XLIO cannot offload traffic in cases where RoCE LAG is enabled too. In RoCE LAG mode, instead of having an IB device per physical port (for example, mlx5_0 and mlx5_1), only one IB device is present for both ports.


Direct Packet Control Plane (DPCP) provides a unified, flexible interface for programming NVIDIA NICs and comes as part of OFED. The DPCP version must be v1.1.20 and above.


A note regarding NGINX:

  • There is no recovery support of NGINX wrk due to a crash of one or more wrks.


TLS Rx offload supports up to 64K concurrent connection.
