RFE - TestPMD Support for Multiple PCI Addresses #81

Closed pradiptapks closed 6 months ago

pradiptapks commented 7 months ago

Issue: In the ShiftonStack NFV use case, the dpdk-testpmd pod cannot forward packets with IO forwarding mode using existing two PCI interface.

Justification: In ShiftonStack deployments, the dpdk-testpmd pod needs to be configured with MAC forwarding mode. To achieve a bidirectional throughput of 100Gbps from multiple trafficgen source, the application requires configuration with more than 2 PCI addresses along with the necessary CPUs and memory hugepages.

The test has been successfully verified through manual configuration in the dpdk-testpmd pod. However, automation through Crucible is necessary to collect metrics from K8s endpoints.
