ice_vsi_ena_outer_insertion(9)

📦 version 7.3.1, in nixpkgs unstable

💅 ice_vsi_ena_outer_insertion — like, the whole kernel API manual vibe ✨

okay so bestie, we're deep in the ice driver today — this is page ice_vsi_ena_outer_insertion(9) from the Kernel API Manual, and honestly? she's niche but she's iconic. buckle up 🎀

🌸 NAME 🌸

ice_vsi_ena_outer_insertion — enable outer VLAN insertion. that's it, that's the whole job. slay 💅

✨ SYNOPSIS ✨

int ice_vsi_ena_outer_insertion (struct ice_vsi *vsi , u16 tpid );

🦋 ARGUMENTS 🦋

  • vsi — the VSI you're configuring, bestie. that's the thing you're touching.
  • tpid — the TPID you wanna enable outer VLAN insertion for. like, the specific tag protocol identifier. no cap.

💖 DESCRIPTION 💖

so the tea is: this function enables outer VLAN insertion via VSI context. super straightforward, right? well — plot twist — there are rules 🫶

rule number one: this should only be used if DVM is supported. if DVM isn't in the picture, this is not the function for you, bestie.
rule number two: this should never be called directly. nope. not ever. it should be part of ice_vsi_vlan_ops if it's needed. it's giving "backstage pass only" energy 💀

and here's the part where you gotta pay attention, because the VSI context only supports a single TPID for insertion and stripping. so setting the TPID for insertion will affect the TPID for stripping too. the way that they're literally entangled 😭 callers need to be aware of this limitation — it's a real one, not a cute little quirk.

okay but what does it actually touch? only the outer VLAN insertion settings and the VLAN TPID. outer VLAN stripping settings are unmodified — left completely alone, untouched, unbothered, thriving. ✨

and the payoff? this allows a VLAN tag with the specified TPID to be inserted in the transmit descriptor. iconic behaviour honestly 🔥
