octep_vf_stop(9)

📦 version 7.3.1, in nixpkgs unstable

💅 octep_vf_stop(9) — from the Kernel API Manual, bestie 🎀

okay so picture this: it's a whole manual page, it lives in the Kernel API Manual, and it's about one (1) function called octep_vf_stop. she's iconic, she's the cleanup queen, and we're gonna get into it. no cap. ✨

🦋 NAME 🦋

octep_vf_stop — literally just stop the octeon network device. that's the whole vibe. she halts. she shuts it down. slay. 💅

🌸 SYNOPSIS 🌸

int octep_vf_stop (struct net_device *netdev );

that's it. that's the signature. return type int, one parameter, done. 🫶

🎀 ARGUMENTS 🎀

  • netdev — pointer to kernel network device. yes bestie it's a struct net_device *, it's giving "the actual device we're about to shut down," and you gotta hand it over. 💖

⭐ DESCRIPTION ⭐

okay so here's what she does, and honestly? she does a LOT:

stop the device Tx/Rx operations, bring down the link, and free up all resources allocated for Tx/Rx queues and interrupts. 💀

like — transmit? stopped. receive? stopped. link? down. queues and interrupts? resources freed. she is the cleanup main character and she is not leaving a single allocated thing behind. periodt. 🔥

ngl, this is the "we're done here" function — everything Tx/Rx and interrupt-shaped gets torn down. don't expect the device to be doing anything useful after this. 🙈

👑 SEE ALSO 👑

the kernel file this all lives in, non-negotiable, iykyk:

./drivers/net/ethernet/marvell/octeon_ep_vf/octep_vf_main.c

and now the whole friend group — every sibling function in the same family, all of them listed, all of them linked, we love a big extended universe 🌈:

literally the entire roster. go read them all. obsessed. 💜

and that's the page!! 🍓 quick sign-off bestie: this came from the source path ./drivers/net/ethernet/marvell... and the date on it is October 2026. so yeah, she's dated, she's sourced, she's octep_vf_stop(9), and she ate. 🧚 ✨
