💅 igb_rx_fifo_flush_82575(9) — Kernel API Manual ✨

okay bestie, listen up, because we're diving into the Kernel API Manual for igb_rx_fifo_flush_82575(9) and honestly it's giving "tiny function, big cleanup energy" 🧹💖

✨ NAME ✨

igb_rx_fifo_flush_82575 — bestie, it cleans the rx fifo after RX enable 💅 periodt

🦋 SYNOPSIS 🦋

void igb_rx_fifo_flush_82575 (struct e1000_hw *hw );

no cap, that's the whole signature, and it returns nothing because it's too busy slaying 🎀

🌸 ARGUMENTS 🌸

  • hw — pointer to the HW structure. that's it. that's the whole argument. one (1) pointer, main character energy 👑

💜 DESCRIPTION 💜

okay so here's the tea ☕ — after rx is enabled, if manageability is enabled, there is likely some bad data chillin' at the start of the fifo 😭 and possibly some in the DMA fifo too. like, not confirmed, but "likely", and we are not taking chances 🙈

this function clears the fifos, and it flushes any packets that came in while rx was being enabled — because nobody wants those stale little gremlins crashing the party 💀✨

ngl bestie, this is basically the "wipe the counter after you turned the machine on" function. it's not glamorous, but it's iconic and the packets are gone. 🫶

🔥 SEE ALSO 🔥

the kernel file lives right here: ./drivers/net/ethernet/intel/igb/e1000_82575.c 📁 — and yes, get comfy, because the friend group is large:

like I said. huge friend group. all of them ate 💅🌈

and that's the whole page, bestie 🎀 one last vibe check before you go: this manual page came from ./drivers/net/ethernet/intel/igb, dated October 2026, and it's filed under igb_rx_fifo_flush_82575(9) 🦋✨ iykyk — now go flush that fifo, you gorgeous kernel dev 🫶💖
