rxe_icrc_check(9)

💅 rxe_icrc_check — the Kernel API Manual, bestie edition

Okay so real talk, this page lives in the Linux Kernel API Manual (section 9, kernel-Doc girlies rise) and it's about one very specific lil function named rxe_icrc_check. It's short, it's sweet, and it absolutely ate. Let's get into it 🫶

---

✨ NAME ✨

rxe_icrc_check — literally computes the ICRC for a packet and compares it to the ICRC that got delivered inside the packet. That's it, that's the whole vibe check 😌

---

🦋 SYNOPSIS 🦋

int rxe_icrc_check (struct sk_buff *skb , struct rxe_pkt_info *pkt );

No cap, that's the whole signature. Copy it exactly, don't be cute with it 💅

---

🌸 ARGUMENTS 🌸

• skb — the packet buffer, aka the actual envelope the data is riding in 📦
• pkt — the packet information, aka the lil info card about that packet 🏷️

---

🌈 RETURN 🌈

• Returns 0 if the values match 👑
• Otherwise it returns an error 💀 (mismatch arc, not the moment)

---

🎀 SEE ALSO 🎀

Bestie, go read the source, it's all right here in the kernel tree:

• Kernel file ./drivers/infiniband/sw/rxe/rxe_icrc.c
• rxe_crc32(9)
• rxe_icrc_hdr(9)
• rxe_icrc_generate(9)

fr fr, this one's a tiny page but the details matter — every flag, every param, every reference. Iconic behavior only ✨
