fcoe_fc_crc(9)

💅 fcoe_fc_crc — like, the CRC queen of frame checksums ✨

okay so this is a page from the Kernel API Manual, section 9, and it's genuinely so straightforward it's almost iconic. bestie, we're talking about one (1) function that crunches a CRC for a frame. that's the whole vibe. let's go 🎀

---

✨ NAME ✨

fcoe_fc_crc — literally calculates the CRC for a given frame. that's it. that's the job. and it ate 💅

---

🦋 SYNOPSIS 🦋

u32 fcoe_fc_crc (struct fc_frame *fp );

---

🌸 ARGUMENTS 🌸

• fp — the frame that's gonna get checksummed. hand it over, she'll do the math 🧮💖

---

⭐ DESCRIPTION ⭐

ok so picture this: you've got a frame, right? and it needs a CRC. this function is the main character that makes it happen — it uses the crc32 routine to calculate the CRC for a frame. no cap, that's the entire plot. short king of a description but she serves 👑

---

🔥 RETURN 🔥

it returns the 32 bit CRC value. that's your answer, bestie — a u32 of pure checksum realness ✨

ngl this page is short but she's perfect exactly as she is. go checksum something, bestie 💜
