dpni_set_queue(9)

💅 dpni_set_queue — from the Kernel API Manual ✨

Okay bestie, gather round, because this one is dpni_set_queue(9) from the Kernel API Manual and she's here to set queue parameters. That's the whole vibe. Let's get into it 🎀

---

✨ NAME ✨

dpni_set_queue — Set queue parameters 💖

---

🦋 SYNOPSIS 🦋

int dpni_set_queue (struct fsl_mc_io *mc_io , u32 cmd_flags , u16 token
, enum dpni_queue_type qtype , u8 tc , u8 index , u8 options , const
struct dpni_queue *queue );

She returns an int, she takes eight arguments, and yes the commas are living their own life. We don't judge. 💀

---

🌸 ARGUMENTS 🌸

• mc_io — pointer to the MC portal's I/O object. Your entry point, your main character portal 🫶
• cmd_flags — command flags; one or more of the 'MC_CMD_FLAG_' values, iykyk
• token — the token of the DPNI object. Gotta have the right token or you're not getting in 👑
• qtype — type of queue. All queue types are supported, although the command is ignored for Tx. Not me calling a function just for it to ignore me 😭
• tc — traffic class, in range 0 to NUM_TCS - 1
• index — selects the specific queue out of the set allocated for the same TC. Value must be in range 0 to NUM_QUEUES - 1 ⭐
• options — a combination of DPNI_QUEUE_OPT_ values that control what configuration options are set on the queue. Mix and match, she's flexible 💅
• queue — the queue structure 🍓

---

💀 RETURN 💀

The original page has the heading and then... nothing. Crickets. A whole empty section. Not me refreshing the manpage looking for the return values 🙈

So fr fr: no return-value description is given on this page. That's just how it is.

./drivers/net/ethernet/freesca... October 2026

That's the source path (truncated as shown, bestie — that's genuinely how it appears) and the date, October 2026, and that's the footer of dpni_set_queue(9). Go set some queue parameters, you got this 💖✨🎀
