ice_vc_ena_vlan_offload(9)

💅 ice_vc_ena_vlan_offload(9) — the kernel API manual, bestie edition 🎀

okay so real talk, this page lives in the Kernel API Manual, and the function's whole name is ice_vc_ena_vlan_offload. Say it three times fast, I dare you. It's the little helper that turns VLAN offload on, and it decides what to turn on based on the ethertype_setting you hand it. Slay.

✨ NAME ✨

ice_vc_ena_vlan_offload — enable VLAN offload based on the ethertype_setting 💖

Like… that's literally the job. It enables VLAN offload, and the flavor of offload is chosen by ethertype_setting. No cap.

---

🌸 SYNOPSIS 🌸

int ice_vc_ena_vlan_offload (struct ice_vsi *vsi , int
(*ena_offload)(struct ice_vsi *vsi, u16 tpid) , u32 ethertype_setting );

Look at that signature. Three arguments, one int coming back at you. Iconic.

---

🦋 ARGUMENTS 🦋

• vsi — the VF's VSI, and it's the thing we use to enable the VLAN offload. Your main character struct, basically 👑
• ena_offload — the function used to enable the VLAN offload. It's a function pointer, bestie: int (*ena_offload)(struct ice_vsi *vsi, u16 tpid). So you're passing in the enabler. Very meta of you 🫶
• ethertype_setting — a u32 stuffed with VIRTCHNL_VLAN_ETHERTYPE_* values, which say which offloads to enable. Like a lil menu of offloads and you're picking off it 🍓

ngl bestie, that SEE ALSO list is a whole friend group chat and you're expected to know every single one of them. iykyk 💀

and that's the page!! 💜 source is ./drivers/net/ethernet/intel/i... (the path got cut off in the footer, we don't gatekeep, we just vibe), dated October 2026, and this whole thing is ice_vc_ena_vlan_offload(9). go enable some offloads, periodt ✨🌈🦋
