58. RNP Poll Mode driver

The RNP ethdev PMD (librte_net_rnp) provides poll mode ethdev driver support for the inbuilt network device found in the Mucse RNP

More information can be found at Mucse, Official Website.

58.1. Supported Chipsets and NICs

  • MUCSE Ethernet Controller N10 Series for 10GbE or 40GbE (Dual-port)

58.1.1. Support of Ethernet Network Controllers

58.1.1.1. PCIe NICs

  • N10G-X2-DC .... Dual-port 10 Gigabit SFP Ethernet Adapter
  • N10G-X4-QC .... Quad-port 10 Gigabit SFP Ethernet Adapter
  • N10G-X8-OC .... Octa-port 10 Gigabit SFP Ethernet Adapter

58.2. Chip Basic Overview

N10 has two functions, each function support multiple ports (1 to 8), which is different of normal PCIe network card (one PF for each port).

58.3. Features

  • Multiple queues for Tx and Rx
  • Receiver Side Steering (RSS) Receiver Side Steering (RSS) on IPv4, IPv6, IPv4-TCP/UDP/SCTP, IPv6-TCP/UDP/SCTP Inner RSS is only supported for VXLAN/NVGRE
  • Promiscuous mode
  • Link state information
  • MTU update
  • MAC/VLAN filtering
  • Jumbo frames
  • Scatter-Gather IO support
  • Port hardware statistics
  • Packet type parsing
  • Checksum offload
  • TSO offload
  • VLAN stripping and VLAN/QINQ insertion

58.4. Prerequisites and Pre-conditions

  1. Prepare the system as recommended by DPDK suite.
  2. Bind the intended N10 device to igb_uio or vfio-pci module.

Now DPDK system is ready to detect N10 ports.

58.5. Limitations or Known issues

X86-32, BSD, Armv7, RISC-V, Windows, are not supported yet.
