dpni_get_qdid(9)

💅 dpni_get_qdid — from the Kernel API Manual

okay so literally welcome bestie, you've stumbled into dpni_get_qdid(9) and honestly? she's a glow-up of a function. this is a kernel API page, it lives in the Kernel API Manual, and she does exactly one thing but she does it flawlessly.

✨ NAME ✨

dpni_get_qdid — get the Queuing Destination ID (QDID) that should be used for enqueue operations 🎯✨

like, that's it. that's the whole vibe. you want the QDID so you can enqueue stuff? she's got you. 🫶

---

🌸 SYNOPSIS 🌸

int dpni_get_qdid (struct fsl_mc_io *mc_io , u32 cmd_flags , u16 token ,
enum dpni_queue_type qtype , u16 *qdid );

one function, five arguments, zero drama. copied exactly, no cap. 💅

---

🎀 ARGUMENTS 🎀

• mc_io — Pointer to MC portal's I/O object. this is the portal babe, the connection to the MC, you gotta hand her the I/O object so she knows where to talk. 🔌
• cmd_flags — Command flags; one or more of 'MC_CMD_FLAG_'. yes literally one or more, you can stack them, she said go off. 🚩
• token — Token of DPNI object. that's your DPNI's little ID badge, she needs to see it before she does anything. 🎫
• qtype — Type of queue to receive QDID for. which queue are we talking about bestie, tell her the type. 🧚
• qdid — Returned virtual QDID value that should be used as an argument in all enqueue operations. ⭐ this is the whole point. she writes the QDID back through this pointer, and then you use that value as an argument in all your enqueue operations. all of them. not some. all. 👑

💀 RETURN 💀

okay so the original page leaves this section literally, completely, totally empty. not me noticing that 😭🙈 — no return description is documented here, so I'm not about to make one up. the function returns an int per the synopsis, and that's genuinely all the page gives us. respect the mystery. 🕵️‍♀️

okay that's the page bestie, go get that Queuing Destination ID 💅✨

and for the sign-off: this one came out of the kernel tree at ./drivers/net/ethernet/freesca... and she's dated October 2026 — so yeah, she's from the future and she's still serving. 🎀🦋🌸
