net_dim_setting(9)

💅 net_dim_setting 💅

okay so this page lives in the Kernel API Manual and it's literally all about net_dim_setting — the glow-up function that initializes DIM's cq mode and gets the worker scheduled. she's the setup bestie, the one who arrives first and gets everything cute before the party starts 🎀

---

✨ NAME ✨

net_dim_setting — initialize DIM's cq mode and schedule worker. that's it, that's the whole job, and she does it flawlessly 💖

---

🌸 SYNOPSIS 🌸

void net_dim_setting (struct net_device *dev , struct dim *dim , bool
is_tx );

note the void — nothing comes back, no receipts, no return value, she just does the thing and leaves 👑

---

🦋 ARGUMENTS 🦋

• dev — target network device. like, the actual netdev you're setting up. the main character, if you will 👑
• dim — DIM context. this is the state blob she's about to sprinkle her magic into ✨
• is_tx — true means the tx direction, false means the rx direction. yes bestie it's a bool, and yes you have to remember which way is which 🙈

ngl the is_tx thing is giving "one flag, two moods" — true = tx, false = rx. no cap. don't flip it 💀
