i40e_fwd_del(9)

💅 i40e_fwd_del — Kernel API Manual, section 9 🎀

okay so this is a page from the Linux kernel API manual (that's the Kernel API Manual, bestie) and we're in section 9, which is where all the driver-internals lore lives. the function we're stanning today is i40e_fwd_del. let's get into it 💖

---

🌸 NAME 🌸

i40e_fwd_del — delete macvlan interfaces. that's the whole vibe. she removes them. periodt.

---

✨ SYNOPSIS ✨

void i40e_fwd_del (struct net_device *netdev , void *vdev );

yes the spacing is exactly like that, don't come for me, i just copy the lore faithfully 🫶

---

🦋 ARGUMENTS 🦋

• netdev — the net device you wanna configure, aka the main character of this operation 👑
• vdev — the macvlan netdevice. this is the one getting yeeted 💀

---

🔥 SEE ALSO 🔥

ngl bestie, this list is long long. like, "she ate and left no crumbs" long. but every single one is here because the manual said so and we don't skip lore in this house 💅

first up, the source of truth itself — the kernel file ./drivers/net/ethernet/intel/i40e/i40e_main.c.

and now… the entire friend group. buckle up 🎀

like i said. long. but she's thorough and we respect her for it 🙈✨

one thing bestie — this page is intentionally just the API surface. no extra caveats, no secret behaviour, no "oh also it does X" tea. if it's not on this page, it's not on this page. iykyk 💀

okay that's the whole page, you ate it up, go forth and delete those macvlan interfaces responsibly 💜 this cutie was brought to you by the Linux kernel API manual, straight out of the source tree at ./drivers/net/ethernet/intel/i40e, dated October 2026 — mwah, bye bestie! 🎀🦋✨
