[PWCI] "doc/guides/nics: split pcap_ring into separate documentation files"#609
Conversation
The documentation had combined to unrelated drivers together. Use AI to split into two separate files: pcap.rst for the pcap PMD and ring.rst for the ring PMD. Changes to pcap.rst: - Use "pcap" consistently instead of mixed "libpcap/pcap/PCAP" naming - Remove Linux-specific references; document support for Linux, FreeBSD, and Windows - Add reference to upstream libpcap documentation - Add multi-queue support section explaining queue count determination and file handle limitations - Use ``--vdev=net_pcap0`` format consistently - Remove deprecated rte_eth_from_pcaps() API section - Improve technical documentation style throughout Changes to ring.rst: - Use ``--vdev=net_ring0`` format consistently - Fix inconsistent "Rings-based/Ring-based" naming - Retain rte_eth_from_rings() API section with usage examples - Improve technical documentation style throughout Signed-off-by: Stephen Hemminger <stephen@networkplumber.org> Signed-off-by: 0-day Robot <robot@bytheb.org>

📝 WalkthroughWalkthroughThe pull request reorganizes NIC driver documentation by splitting the combined pcap_ring.rst file into two separate documentation files—pcap.rst for the Pcap Poll Mode Driver and ring.rst for the Ring Based Poll Mode Driver—and updates the driver index accordingly. Changes

<code_context>
+using the pcap driver, to be created at application startup time during EAL initialization.
+
+To do so, pass the ``--vdev=net_pcap0`` parameter to the EAL.
+This parameter accepts options to allocate and use pcap-based Ethernet transparently by the application.
+This can be used, for example, for testing on a virtual machine where there are no Ethernet ports.
+
</code_context>
<issue_to_address>
**suggestion (typo):** Consider rephrasing "transparently by the application" to the more idiomatic "transparently to the application".
The current phrasing is grammatically awkward; consider wording like "in a way that is transparent to the application" for smoother readability.

**issue (typo):** Add "the" before "interface" for correct grammar.
Consider updating this sentence to: "an error if the interface is down" for correct grammar.

an error if the interface is down, and the PMD itself won't change the status

- ring[0] = rte_ring_create("R0", RING_SIZE, SOCKET0, RING_F_SP_ENQ|RING_F_SC_DEQ);
- ring[1] = rte_ring_create("R1", RING_SIZE, SOCKET0, RING_F_SP_ENQ|RING_F_SC_DEQ);
-
- /* create two ethdev's */
-
- port0 = rte_eth_from_rings("net_ring0", ring, NUM_RINGS, ring, NUM_RINGS, SOCKET0);
</code_context>
<issue_to_address>
**issue (typo):** Use the correct plural form "ethdevs" instead of "ethdev's".
The apostrophe implies possession rather than plurality. Please update the comment text to use the plural form, e.g. `/* create two ethdevs */`.
```suggestion
/* create two ethdevs */
```

### Comment 4
<location> `doc/guides/nics/ring.rst:115` </location>
<code_context>
+Once an ethdev has been created for a ring-based PMD,
+it should be configured and started in the same way as a regular Ethernet device:
+call rte_eth_dev_configure() to set the number of receive and transmit queues,
+then call rte_eth_rx_queue_setup() / tx_queue_setup() for each of those queues,
+and finally call rte_eth_dev_start() to allow transmission and reception of packets to begin.
</code_context>
<issue_to_address>
**issue:** The TX queue setup API name appears incomplete; likely should be rte_eth_tx_queue_setup().
To match the RX API and actual DPDK ethdev names, this should reference `rte_eth_rx_queue_setup() / rte_eth_tx_queue_setup()`. The current `tx_queue_setup()` form may mislead readers searching for the correct API.
