ice_tx_prepare_vlan_flags(9)

💅 ice_tx_prepare_vlan_flags(9) — or, "getting your Tx VLAN flags cute before the HW sees them"

okay so this is a page straight out of the Kernel API Manual 📖✨ and it's all about one little helper that preps generic Tx VLAN tagging flags for the hardware. grab a strawberry drink 🍓 and let's go.

---

✨ NAME ✨

ice_tx_prepare_vlan_flags — prepare generic Tx VLAN tagging flags for HW 💅

---

🦋 SYNOPSIS 🦋

void ice_tx_prepare_vlan_flags (struct ice_tx_ring *tx_ring , struct
ice_tx_buf *first );

---

🎀 ARGUMENTS 🎀

• tx_ring — the ring you're sending that buffer on. like, the venue. the venue matters 🫶
• first — pointer to struct ice_tx_buf. yes bestie, that's the one 🌸

---

🔥 DESCRIPTION 🔥

so what does it actually do? it checks the skb and then sets up, correspondingly, several generic transmit flags related to VLAN tagging for the HW — the big ones being VLAN, DCB, etc. ⭐

that's it. that's the whole vibe. it's not out here doing the transmit, it's doing the paperwork before the transmit, and honestly? iconic. 👑

ngl this one is a "know it exists" function more than a "call it yourself" function — it's part of the ice Tx path and it's just setting flags, no return value, no drama 💀
