igb_setup_tx_resources(9)

💖 NAME 💖

igb_setup_tx_resources — allocate Tx resources (Descriptors)

okay so real talk, bestie, this little icon lives in the Kernel API Manual, section 9, and it's the function that gets your transmit resources (descriptors) set up. it's giving "backend bestie doing the unglamorous work so the packets can slay later." 💅

---

✨ SYNOPSIS ✨

int igb_setup_tx_resources (struct igb_ring *tx_ring );

---

🎀 ARGUMENTS 🎀

• tx_ring — tx descriptor ring (for a specific queue) to setup

yep, that's the one and only thing you hand it: the tx descriptor ring for a specific queue. not all the queues. the one. main character energy for a single ring, honestly. 🫶

---

🦋 DESCRIPTION 🦋

Return 0 on success, negative on failure.

that's literally it, no cap. zero means it ate and everything's fine, and a negative value means nope, it didn't work out. that's the entire vibe check. 😭✨
