ice_vf_ena_vlan_promisc(9)

💅 ice_vf_ena_vlan_promisc(9) — bestie's Kernel API Manual era

okay so this is a page straight out of the Kernel API Manual, and it's about one very specific little function. no cap, it does exactly one job and it wants you to check first. let's get into it 🫶

---

✨ NAME ✨

ice_vf_ena_vlan_promisc — enables Tx/Rx VLAN promiscuous for the VLAN 💅

---

🦋 SYNOPSIS 🦋

int ice_vf_ena_vlan_promisc (struct ice_vf *vf , struct ice_vsi *vsi ,
struct ice_vlan *vlan );

like, that's the whole signature. three structs, one int coming back at you ✨

---

🎀 ARGUMENTS 🎀

• vf — the VF you're enabling VLAN promisc on. this is the main character fr.
• vsi — the VF's VSI, aka the thing you actually use to enable VLAN promiscuous mode.
• vlan — the VLAN you're doing the enabling for. the VLAN in question. iconic.

---

🌸 DESCRIPTION 🌸

okay so here's the vibe check 👑 — this function should only be called if VLAN promiscuous mode is allowed. like, that's a hard prerequisite bestie, don't just yeet a call at it and hope 💀 and how do you know if it's allowed? you check with ice_is_vlan_promisc_allowed. that's the gatekeeper. iykyk.

no cap: if VLAN promiscuous mode isn't allowed, this is not your moment. check with ice_is_vlan_promisc_allowed first. periodt. 🙈
