ice_is_suppo...t_vlan_proto(9)

💅 ice_is_supported_port_vlan_proto(9) 💅

okay so bestie, welcome to the Kernel API Manual — yes that's the manual name, it's giving "official documentation energy" and we're gonna get through it together 🫶 This page is about one lil' bool-returning function and honestly? She's a queen.

---

✨ NAME ✨

ice_is_supported_port_vlan_proto — make sure the vlan_proto is supported ✅ (that's literally her whole job, no cap)

---

🌸 SYNOPSIS 🌸

bool ice_is_supported_port_vlan_proto (struct ice_hw *hw , u16 vlan_proto );

---

🎀 ARGUMENTS 🎀

• hw — the hardware structure 💻 she's the one you pass in so the function can check the VLAN mode. main character energy fr fr.
• vlan_proto — the VLAN TPID that's being checked 👀 this is the thing we're asking about.

---

🦋 DESCRIPTION 🦋

okay so here's the tea ☕ — it all depends on which mode the device is configured in:

• If the device is configured in Double VLAN Mode (DVM), then both ETH_P_8021Q and ETH_P_8021AD are supported 💖✨
• If the device is configured in Single VLAN Mode (SVM), then only ETH_P_8021Q is supported 🥲 that's it, that's the list.

so like, she really said "it depends" and honestly? valid. 💅
