e1000_setup_tx_resources(9)

🌸 e1000_setup_tx_resources ✨

okay so bestie, welcome to the Kernel API Manual entry for e1000_setup_tx_resources — yes the whole name is a mouthful, we don't make the rules 💅 but we DO explain them, so stick with me.

---

💖 NAME 💖

e1000_setup_tx_resources — allocate Tx resources (Descriptors) 🎀

like, it's the function that gets your transmit side its stuff. that's the vibe.

---

🦋 SYNOPSIS 🦋

int e1000_setup_tx_resources (struct e1000_adapter *adapter , struct
e1000_tx_ring *txdr );

---

✨ ARGUMENTS ✨

• adapter — the board private structure 🫶 your whole adapter's little home base, the private one, you know the one.
• txdr — the tx descriptor ring (for a specific queue) to setup 🌈 note that it's for a specific queue, so don't be out here assuming it does all of them, it's very much a one-queue-at-a-time situation.

---

👑 DESCRIPTION 👑

Return 0 on success, negative on failure 🌟 that's it, that's the whole description, and honestly? iconic. short and honest. if you get 0 you slayed, if you get a negative number something did NOT go according to plan 😭
