fm10k_fifo_crc(9)

💅 fm10k_fifo_crc — the kernel API manual page, bestie edition 🎀

okay so real talk, this is fm10k_fifo_crc(9) from the Kernel API Manual and it's literally the little icon that generates a CRC based off of FIFO data. yes queen, checksums. we love a data-integrity moment ✨

✨ NAME ✨

fm10k_fifo_crc — generate a CRC based off of FIFO data 🧚

---

🦋 SYNOPSIS 🦋

u16 fm10k_fifo_crc (struct fm10k_mbx_fifo *fifo , u16 offset , u16 len ,
u16 seed );

she takes four things and gives you back a u16, that's the whole vibe 💜

---

🌸 ARGUMENTS 🌸

• fifo — pointer to FIFO. like, the actual queue we're poking at 🫶
• offset — offset point for start of FIFO. where we start, iykyk
• len — number of DWORDS words to process. yes, DWORDS, it said what it said 💀
• seed — seed value for CRC. gotta start somewhere bestie

---

🌈 DESCRIPTION 🌈

so basically this function generates a CRC for some region of the FIFO. that's it, that's the whole personality. it picks a region, it crunches it, it hands back a CRC. iconic, no notes 💅

okay that's the page, bestie 🫶 this little drop came out of ./drivers/net/ethernet/intel/f... (yes, it's truncated like that, don't @ me) with an October 2026 date stamp, and it's fm10k_fifo_crc(9) all day. go forth and CRC responsibly, periodt 💖 ⭐
