ice_vsi_add_vlan_zero(9)

🦋 ice_vsi_add_vlan_zero(9) 🦋

okay so bestie, welcome to the Kernel API Manual page for ice_vsi_add_vlan_zero(9) — manual name folded in right at the top like a lil bookmark 🎀. This is the function that adds VLAN 0 filter(s) for a VSI, and we're gonna get into it.

🌸 NAME 🌸

ice_vsi_add_vlan_zero — add VLAN 0 filter(s) for this VSI 💖

✨ SYNOPSIS ✨

int ice_vsi_add_vlan_zero (struct ice_vsi *vsi );

🎀 ARGUMENTS 🎀

• vsi — VSI used to add VLAN filters 🫶

💅 DESCRIPTION 💅

So in Single VLAN Mode (SVM), single VLAN filters via ICE_SW_LKUP_VLAN are based on the inner VLAN ID, which means the VLAN TPID (i.e. 0x8100 or 0x888a8) doesn't matter. Iconic, honestly. In Double VLAN Mode (DVM), outer/single VLAN filters via ICE_SW_LKUP_VLAN are based on the outer/single VLAN ID + VLAN TPID. Different vibe, different rules ✨.

For both modes, add a VLAN 0 + no VLAN TPID filter to handle untagged traffic when VLAN pruning is enabled. Also, this handles VLAN 0 priority tagged traffic in SVM, since the VLAN TPID isn't part of filtering. Lowkey elegant 😌.

If DVM is enabled, then an explicit VLAN 0 + VLAN TPID filter needs to be added to allow VLAN 0 priority tagged traffic in DVM, since the VLAN TPID is part of filtering. No skipping that part, bestie — it's giving required extra step 💅.
