i40e_vlan_rx_add_vid_up(9)

💖 i40e_vlan_rx_add_vid_up(9) 💖

okay so you're reading the Kernel API Manual bestie, and this page is all about i40e_vlan_rx_add_vid_up — it lives in section 9, it's a kernel thing, and yes it's giving "niche but essential." let's get into it 💅

---

✨ NAME ✨

i40e_vlan_rx_add_vid_up — add a vlan id filter to HW offload in UP path 🦋

that's it. that's the whole vibe. a vlan id filter, straight to the hardware offload, specifically in the UP path. no cap.

---

🎀 SYNOPSIS 🎀

void i40e_vlan_rx_add_vid_up (struct net_device *netdev , __be16 proto ,
u16 vid );

it returns void, so like... don't go looking for a return value. there isn't one. it just does the thing 🫶

---

🌸 ARGUMENTS 🌸

• netdev — the network interface to be adjusted. this is the one getting messed with, bestie.
• proto — unused protocol value. literally unused. it's there, it's a parameter, it's not doing anything. icon behavior honestly 💀
• vid — the vlan id to be added. this one actually matters ✨

---

🔥 SEE ALSO 🔥

the kernel file it lives in:

• ./drivers/net/ethernet/intel/i40e/i40e_main.c

and then, and I cannot stress this enough, an absolutely iconic amount of cross-references. like, we're not skipping ANY of them. every single one, bestie. here we go 👑

and that's the page, bestie!! 🧚 stay hydrated, go read your driver source, and remember — the proto param was never doing anything 💜

this lil cutie came from ./drivers/net/ethernet/intel/i40e and it's dated October 2026 — mwah, sending you off with a kiss and a void return type 😭🫶
