dpni_add_vlan_id(9)

💅 dpni_add_vlan_id — hey bestie, let's talk VLAN ID filters

okay so real talk, this is a page from the Kernel API Manual (that's the manual name, bestie, in case you were wondering 💖) and it's about one very specific little function: dpni_add_vlan_id. It adds a VLAN ID filter. That's the whole vibe. Slay.

---

✨ NAME ✨

dpni_add_vlan_id — Add VLAN ID filter 🎀

---

🌸 SYNOPSIS 🌸

int dpni_add_vlan_id (struct fsl_mc_io *mc_io , u32 cmd_flags , u16
token , u16 vlan_id , u8 flags , u8 tc_id , u8 flow_id );

no cap, that's exactly how it's written, commas and spacing and all. iconic honestly.

---

🦋 ARGUMENTS 🦋

• mc_io — Pointer to MC portal's I/O object. like, your entry point to the whole thing 🫶
• cmd_flags — Command flags; one or more of 'MC_CMD_FLAG_' ⭐
• token — Token of DPNI object 🔑
• vlan_id — VLAN ID to add. the actual star of the show 💅
• flags — okay so this one has two moods, and the page spells them out exactly:
  • 0 — tc_id and flow_id will be ignored. Pkt with this vlan_id will be passed to the next classification stages
  • DPNI_VLAN_SET_QUEUE_ACTION — Pkt with this vlan_id will be forward directly to queue defined by the tc_id and flow_id 😭 (yes that's the original wording, "will be forward", keeping it verbatim because the facts do not change, bestie)
• tc_id — Traffic class selection (0-7) 🌈
• flow_id — Selects the specific queue out of the set allocated for the same as tc_id. Value must be in range 0 to NUM_QUEUES - 1 👑

---

🔥 RETURN 🔥

bestie. the RETURN section is literally empty in the original. like, nothing. void. a whole empty section 💀 so I'm not gonna invent anything for you — nothing is listed here, no cap, that's the tea 🙈

and that's the whole page, bestie 🎀✨

cute little sign-off before you go: the source/version line at the bottom reads ./drivers/net/ethernet/freesca... (yes, truncated exactly like that, we love a cliffhanger 💀) and it's dated October 2026 🗓️💜 and then it just says dpni_add_vlan_id(9) again because manpages love a little outro. bye bestie, go filter those VLANs 💅🌸
