irdma_send_ack(9)

💌 irdma_send_ack

okay so bestie, welcome to irdma_send_ack — straight out of the Kernel API Manual, section 9 (that's the kernel-functions girlies 🎀). It does exactly one thing and it does it slayfully: it sends an ACK packet. That's the whole vibe. Let's get into it ✨

---

🌸 NAME

irdma_send_ack — send ACK packet 💅

---

🦋 SYNOPSIS

void irdma_send_ack (struct irdma_cm_node *cm_node );

that's it. that's the whole signature. void return, one arg, no drama. periodt 💜

---

✨ ARGUMENTS

• cm_node — this is the connection's node, like the little ID card for the connection you're ACK-ing. hand it over and it's giving exactly what the function needs 🫶

---

like I said. whole friend group. go say hi 💖

ngl this one's a short page because the function is short. don't overthink it, bestie — hand it the cm_node, get an ACK sent. that's the tea 🍓

---

and that's the page!! this little icon lives in ./drivers/infiniband/hw/irdma, stamped October 2026, and it will forever be irdma_send_ack(9) in my heart 👑💜 mwah, go send some ACKs 🧚‍♀️
