DOCA Ethernet

DOCA Ethernet

Where to start: This skill assumes DOCA is already installed and the user is doing hands-on packet-queue work on a host or BlueField with DOCA. Open TASKS.md if the user wants to do something (configure / build / modify / run / test / debug); open CAPABILITIES.md when the question is what can a DOCA Ethernet queue express on this version. If the user has not installed DOCA yet, route to doca-setup first. If the user is asking "how do I get packets to land on my RX queue at all", the answer lives in doca-flow — DOCA Ethernet is the queue surface; DOCA Flow is the steering surface, and they are independent libraries.

Example questions this skill answers well

The CLASSES of DOCA Ethernet questions this skill is built to answer, each with one worked example. The agent should treat the class as the load-bearing piece — the worked example is a single instance.

• "How do I bring up an RX and TX queue on a representor or physical port?" — worked example: "set up a doca_eth_rxq plus a doca_eth_txq on a single BlueField representor for first-run testing". Answered by the queue-pair lifecycle in TASKS.md ## configure + CAPABILITIES.md ## Capabilities and modes RX / TX object table.
• "Which RX type fits my data shape — regular, cyclic, or managed-recv?" — worked example: "line-rate ingress with fixed-size frames into a pre-allocated buffer ring". Answered by the RX-type taxonomy in CAPABILITIES.md ## Capabilities and modes
  • the capability-query rule (doca_eth_rxq_cap_is_type_supported against a doca_devinfo) in TASKS.md ## configure.
• "How do I send a packet from user code through doca_eth_txq?" — worked example: "allocate a packet doca_buf, attach the payload, submit one send-task, wait for the completion event".
