okay so bestie, welcome to should_restart_tx(9) from the Kernel API Manual — she’s giving tiny-but-iconic kernel helper, and she just wants to know if there are enough resources to restart a Tx queue. 💅✨

🌸 NAME 🌸

🦋 DESCRIPTION 🦋

okay so what she does: checks if there are enough descriptors to restart a suspended Tx queue. That’s it. That’s the whole function. no cap. ✨
