e1000_free_tx_resources(9)

💅 e1000_free_tx_resources — the Kernel API Manual, bestie edition

okay so this is from the Kernel API Manual, manual name e1000_free_tx_resources(9), and it's about exactly one thing: yeeting the transmit software resources for a single queue. short page. iconic behavior. let's get into it 🫶

---

✨ NAME ✨

e1000_free_tx_resources — Free Tx Resources per Queue

like, per queue. one queue. not all of them. remember that, it matters later 👀

---

🌸 SYNOPSIS 🌸

void e1000_free_tx_resources (struct e1000_adapter *adapter , struct
e1000_tx_ring *tx_ring );

returns nothing (void, she's not giving you a status code, she's just doing the thing), and it takes two args. periodt.

---

🎀 ARGUMENTS 🎀

• adapter — the board private structure. it's the adapter. it's got all the private board tea in it 🔥
• tx_ring — the Tx descriptor ring for a specific queue. that's the ring you're about to free, no cap.

---

🦋 DESCRIPTION 🦋

Free all transmit software resources.

that's literally it, that's the whole description, and honestly? obsessed with the brevity. it frees all the transmit software resources. software resources specifically — so like, the software side of the Tx stuff, not out here making claims about anything else. don't put words in her mouth 💅

lowkey a reminder: this frees resources for one queue. if you want all the Tx resources, that's a different function in that list above (e1000_free_all_tx_resources(9), iykyk). this page only promises the one ring 💀

and that's the whole page bestie, ty for coming to my ted talk 🧚 this little gem is from the Kernel API Manual, source ./drivers/net/ethernet/intel/e..., dated October 2026, and the page itself is e1000_free_tx_resources(9). slay, go free those Tx software resources 💖✨🎀
