We're working on a white paper which should be available soon. In the meantime, there's more information on these technologies at:
https://www-ssl.intel.com/content/www/us/en/communications/cache-monitoring-cache-allocation-technologies.html

> IPsec Sample Application: A sample application will be created which
> will show how DPDK and the new cryptodev API can be used to implement
> IPsec. Use of the cryptodev API will allow either hardware or software
> encryption to be used. IKE will not be implemented so the SA/SP DBs will
> be statically configured.
> 
> Cryptodev Support for SNOW 3G: The cryptodev API, and the hardware and
> software crypto PMDs that it supports, will be enhanced to support the
> SNOW 3G cipher.
> 
> External Mempool Manager: SoCs and some software applications that use
> DPDK have their own memory allocation capabilities. This feature will
> allow DPDK to work with an external mempool manager.
> 
> Packet Framework (Edge Router Use Case):
> - Further performance tuning for the vPE use case.
> - Support for load balancing within a pipeline.
> - Support for CPU utilization measurements within a pipeline.
> - Improvements for the functional pipelines, tables and ports.
> 
> Ethdev Enhancements: Merge parts of the Packet Framework ports library
> into ethdev so they can be used without the Packet Framework. The
> initial focus is to add support for buffered TX to ethdev.
> 
> Live Migration: The main infrastructure to support live migration of VMs
> was implemented over the last few DPDK releases via the Link Bonding and
> PCI Hot Plug features. This feature will involve further investigation,
> prototyping and enhancements to improve live migration support in DPDK.
> 
> Tcpdump Support: Support for tcpdump will be added to DPDK. This will
> improve usability and debugging of DPDK applications.
> 
> Increase Next Hops for LPM (IPv4): The number of next hops for IPv4 LPM
> is currently limited to 256. This will be extended to allow a greater
> number of next hops.
> 
> Fm10k Enhancements: FTAG based forwarding, and performance tuning
> 
> Support Intel Resource Director Technology: A library will be added to
> DPDK to support the following Intel CPU technologies:
> - CAT - Cache Allocation Technology (LLC aka L3)
> - CDP - Code Data Prioritization (extension of CAT)
> - CMT - Cache Monitoring Technology (LLC)
> - MBM - Memory Bandwidth Monitoring, to local and remote RAM
> These technologies are currently available via cgroups and perf, but
> this feature will provide closer integration with DPDK and a sample
> application showing how they can be used.
> 
> I40e Enhancements:
> - Flow Director input set Alignment
> - Ethertype configuration for QinQ support
> - Flow Director Support for Tunnels (QinQ, GRE/NVGRE, VXLAN)
> - Flow Director Support for IP Proto and IP TOS
> - VEB switching
> - Floating VEB
> - IPGRE Support
> - Set VF MAC address
> - Rework PCIe extended tag enabling by using DPDK interfaces
> 
> Virtio/Vhost Enhancements:
> - Virtio 1.0 support
> - Vhost software TSO
> - Vhost/virtio performance tuning
> 
> Container Enhancements:
> - Virtio for containers
> - Hugetlbfs mount point size
> - Cgroup resource awareness
> - Enable short-lived DPDK applications
> 
> Generic Tunneling API:
> - Implement virtual flow device framework
> - Implement generic virtual device management APIs, including the
> following callback functions:
>   - flow_ethdev_start/stop/configure/close/info_get
>   - ethdev_rx/tx_queue_setup/release
>   - flow_ethdev_tunnel_configure/setup/destroy
>   - flow_ethdev_tunnel_pkt_decap/encap
> - Implement flow device PMD drive APIs
>   - rte_eth_flow_dev_create/remove/ others
> - Integrate VXLAN protocol (including VXLAN decap/encap optimization)
> into this framework only on i40e.
