This is a maintenance release in the Napatech Link-Inline Software 3.0 series (see features below): This release updates the FPGA image relevant to the 3.0 series:
We recommend to use the this latest version of this image due to updates done in 3.0.3
This release resolves these Support issues compared to previous maintenance release:
- Support-ID 45136: dpdk-testpmd is seg faulting if setup with more than Tx=32 and Rx=32 queues
- Support-ID 45164: the NIC is sending out a corrupted packet if the UPF payload is lesser than 14B (Link Inline 3.0.5)
- Support-ID 45183: testpmd command bad arguments
- Support-ID 45216: incorrect checksum when applying gtp header encapsulation to ICMP/TCP packets
Features in introduced in the Napatech Link-Inline Software 3.0.0:
- Support for 2x100G port speed on NT200A02 (FPGA image 9563-55-16) with Native DPDK driver (version 22.11.1) with support for the following features
- Flow lookup (based on Flow Matcher)
- Policy lookup and enforcement (based on leaky bucket algorithm)
- Support for up to 4 policies
- MBR Policing support
- IPv4 and IPv6 support
- Flow mirroring support
- Subnet filtering (E.g. Can be used for subnet filtering on a per gNB basis in a 5G networks)
- Scatter-gather buffer system – to improve packet latency through the slow path (all packets going to the host system)
- GTP de-/en-capsulation
- NAT support (IPv4 only)
- DSCP tagging support
- Billing Counters
- Kubernetes support using Napatech Device Plugin
- VFs and support for connecting to VFs through Kubernetes containers
- rte_flow configuration through remote app that access PFs thought Linux sockets
- Inline UPF Demo application
- Limited features in this release
- Reduced Flow learning rate (in the 150k/s range)
