rte_eth_vmdq_dcb_conf(3)

📦 version 26.03, in nixos 26.05, nixpkgs unstable

💖 hey bestie, welcome to rte_eth_vmdq_dcb_conf(3) 💖

okay so this is the rte_eth_vmdq_dcb_conf(3) page from the Library Functions Manual, and it’s literally the struct that tells an Ethernet port how to do VMDq+DCB. grab your lil snack, we’re getting into it 🍓✨

🌸 NAME 🌸

rte_eth_vmdq_dcb_conf — the VMDq+DCB configuration struct, no cap 💅

🦋 SYNOPSIS 🦋

#include <rte_ethdev.h>

🎀 Data Fields 🎀

       enum rte_eth_nb_pools nb_queue_pools
       uint8_t enable_default_pool
       uint8_t default_pool
       uint8_t nb_pool_maps
       struct {
          uint16_t vlan_id
          uint64_t pools
       } pool_map [RTE_ETH_VMDQ_MAX_VLAN_FILTERS]
       uint8_t dcb_tc [RTE_ETH_DCB_NUM_USER_PRIORITIES]

💅 Detailed Description 💅

A structure used to configure the VMDq+DCB feature of an Ethernet port. iconic behavior, honestly 👑

Using this feature, packets are routed to a pool of queues, based on the VLAN ID in the VLAN tag, and then to a specific queue within that pool, using the user priority VLAN tag field. it’s giving “traffic gets sent to exactly the right lil queue” energy ✨

A default pool may be used, if desired, to route all traffic which does not match the VLAN filter rules. so yes, the unmatched traffic can still have a home 🫶

🔥 Field Documentation 🔥

🌈 enum rte_eth_nb_pools nb_queue_pools

With DCB, 16 or 32 pools. those are the numbers, bestie — 16 or 32, periodt 💀

Definition at line 995 of file rte_ethdev.h.

🌸 uint8_t enable_default_pool

If non-zero, use a default pool. simple as that ✨

Definition at line 996 of file rte_ethdev.h.

🎀 uint8_t default_pool

The default pool, if applicable. yes, only if it applies, bestie 💅

Definition at line 997 of file rte_ethdev.h.

🦋 uint8_t nb_pool_maps

We can have up to 64 filters/mappings. sixty-four is the limit, noted and slayed 📝

Definition at line 998 of file rte_ethdev.h.

💜 uint16_t vlan_id

The VLAN ID of the received frame. it’s the VLAN ID, in the received frame, exactly 🌷

Definition at line 1000 of file rte_ethdev.h.

⭐ uint64_t pools

Bitmask of pools for packet Rx. bitmask, pools, packet Rx — got it 💫

Definition at line 1001 of file rte_ethdev.h.

👑 struct { ... } pool_map[RTE_ETH_VMDQ_MAX_VLAN_FILTERS]

VMDq VLAN pool maps. that’s the whole vibe of this field 🗺️

💖 uint8_t dcb_tc[RTE_ETH_DCB_NUM_USER_PRIORITIES]

Selects a queue in a pool. yes, it picks the queue inside the pool 🎯
