irdma_mcast_cqp_op(9)

💅 irdma_mcast_cqp_op — from the Kernel API Manual, section 9 🎀

okay bestie, so this one is irdma_mcast_cqp_op(9) and no cap, it's literally the "do a mcast cqp operation" page. Short and sweet, but we're gonna give it the full main character treatment ✨

---

✨ NAME ✨

irdma_mcast_cqp_op — perform a mcast cqp operation 🦋

---

🌸 SYNOPSIS 🌸

int irdma_mcast_cqp_op (struct irdma_device *iwdev , struct
       irdma_mcast_grp_info *mc_grp_ctx , u8 op );

like, that's the whole signature, go off 👑

---

💖 ARGUMENTS 💖

• iwdev — the irdma device itself, your main character struct 🫶
• mc_grp_ctx — the mcast group info, all the multicast tea 🍓
• op — the operation, a humble u8 doing big things 💅

---

🔥 DESCRIPTION 🔥

it returns an error status. that's it. that's the description. iconic minimalism, honestly 😭✨

ngl, this page is short — but every word of it is load-bearing, so don't skip the return value, fr fr 💀
