ice_vf_vsi_...cy_vlan_mode(9)

✨ ice_vf_vsi_cfg_dvm_legacy_vlan_mode(9) ✨

okay bestie, welcome to the Kernel API Manual 💅 this one's a deep cut from the ice driver and it's giving "niche but essential," honestly iconic.

---

🌸 NAME 🌸

ice_vf_vsi_cfg_dvm_legacy_vlan_mode — sets up the VLAN mode for the old-school VFs when you're running in DVM 🫶

---

🎀 SYNOPSIS 🎀

void ice_vf_vsi_cfg_dvm_legacy_vlan_mode (struct ice_vsi *vsi );

---

🦋 ARGUMENTS 🦋

• vsi — the VF's VSI that's getting configured, that's the one we're dressing up ✨

---

💖 DESCRIPTION 💖

so here's the vibe check 👑 — you should only call this when all three of these are true, no cap:

• Double VLAN Mode (DVM) is enabled ✅
• there is not a port VLAN enabled on this VF ✅
• and the VF negotiates VIRTCHNL_VF_OFFLOAD_VLAN ✅

if any of those is a no, this function is not the main character, okay? 🙈

what it actually does: it sets up the VF VSI's inner and outer ice_vsi_vlan_ops, and also initializes software only VLAN mode (i.e. allow all VLANs) 🎀 literally that simple.

and the last bit is kind of the genius part ngl — for any functions that might get called during the lifetime of the VF, it uses no-op implementations, so those methods do nothing and just... succeed 🧚 lowkey the dream coping mechanism fr fr 💀
