dpni_add_qos_entry(9)

💅 dpni_add_qos_entry(9) — the Kernel API Manual page, but make it cute

okay so bestie, welcome to the Kernel API Manual page for dpni_add_qos_entry(9) — yes the manual name is Kernel API Manual and yes we're folding that in right at the top because we're polite 🎀

This one's got main character energy honestly: it's the call that adds a QoS mapping entry, i.e. the thing that helps pick which traffic class your packets roll with. Slay.

✨ NAME ✨

dpni_add_qos_entry — add a QoS mapping entry (the whole point of which is to select a traffic class 😌)

---

🦋 SYNOPSIS 🦋

int dpni_add_qos_entry (struct fsl_mc_io *mc_io , u32 cmd_flags , u16
       token , const struct dpni_rule_cfg *cfg , u8 tc_id , u16 index );

like, look at her. five params deep and still iconic. 🔥

---

🌸 ARGUMENTS 🌸

• mc_io — pointer to the MC portal's I/O object. your little handle to the portal, no cap 🫶
• cmd_flags — command flags; one or more of MC_CMD_FLAG_. pick your flags, be free ✨
• token — token of the DPNI object. it's literally the DPNI's name tag 🎀
• cfg — the QoS rule you wanna add. this is the rule itself, the whole vibe 💅
• tc_id — traffic class selection, range 0-7. pick a lane, any lane 🌈
• index — location in the QoS table where to insert the entry. Only relevant if MASKING is enabled for QoS classification on this DPNI — and heads up, it is ignored for exact match. so if you're doing exact match, don't stress about it bestie, it's not reading your index at all 🙈

ngl the index caveat is the one thing people get wrong, so like — masking = matters, exact match = ignored. periodt. 💀

⭐ RETURN ⭐

so this section on the page is genuinely just... empty. girl left the chat 😭 the manpage gives us the heading and then dips. no return values listed, no nothing. iconic but unhelpful — don't come for me, I'm only reporting what's on the page 🫶

okay that's the whole page!! mwah 💜

tiny sign-off before you go: the source path at the bottom is literally truncated to ./drivers/net/ethernet/freesca... (yes, the page itself did that, not me 🙈) and the date on this edition is October 2026. she's fresh. go forth and classify your traffic, bestie 🌟
