💅 liquidio_tx_timeout(9)

okay so bestie, welcome to the liquidio_tx_timeout(9) page in the Kernel API Manual ✨ this one's short and sweet, like a little snack before the big kernel docs meal 🍓

---

🎀 NAME 🎀

liquidio_tx_timeout — Network device Tx timeout, no cap 💖

it's literally the handler that fires when your network device's transmit path goes "bestie… I'm not sending anything" 😭

---

✨ SYNOPSIS ✨

void liquidio_tx_timeout (struct net_device *netdev , unsigned int
txqueue );

that's the whole signature, gorgeous. void return, two args, we move 💅

---

🦋 ARGUMENTS 🦋

• netdev — pointer to network device 🫶 this is the struct net_device in question, the main character of the operation
• txqueue — index of the hung transmit queue 💀 key word: hung. this tells you which transmit queue has been sitting there not moving, and yes it's an unsigned int
