iavf_set_queue_vlan_tag_loc(9)

💅 iavf_set_queue_vlan_tag_loc(9) 💅

okay bestie, welcome to the Kernel API Manual — this page is all about iavf_set_queue_vlan_tag_loc, and honestly it's a little function with main character energy. Let's get into it 🫶

---

✨ NAME ✨

iavf_set_queue_vlan_tag_loc — set location for VLAN tag offload 🌸

---

🦋 SYNOPSIS 🦋

void iavf_set_queue_vlan_tag_loc (struct iavf_adapter *adapter );

(no cap, that's the whole signature — a void that takes one pointer and does the thing 😌)

---

🎀 ARGUMENTS 🎀

• adapter — the board private structure, aka the struct that knows all the tea about this board 💖

---

👑 DESCRIPTION 👑

so here's the vibe: depending on what capabilities got negotiated, the VLAN tag needs to be inserted and/or stripped in certain descriptor fields. literally just how the hardware wants it, iykyk.

and instead of checking the offload capability bits every single time in the hot path (😭 performance queen, we do not do that), this function caches the location in the ring specific flags. so the hot path just reads the cached answer instead of doing the whole capability-bit scavenger hunt again. periodt 💅✨
