dev_uc_init(9)

💖 dev_uc_init(9) — the Kernel API Manual, bestie edition 💖

okay so real talk, we're in the Kernel API Manual today and the page is called dev_uc_init. it's a tiny one but it's iconic, i promise. let's get into it 🎀

---

✨ NAME ✨

dev_uc_init — init the unicast address list 🦋

like, the whole personality of this function is "set the unicast address list up so it's ready to go."

---

✨ SYNOPSIS ✨

void dev_uc_init (struct net_device *dev );

that's it. that's the whole vibe. no return value, nothing spicy. 🫶

---

✨ ARGUMENTS ✨

• dev — the device. literally the device. that's your one and only parameter, bestie 💅

---

✨ DESCRIPTION ✨

Init unicast address list. 😭 yes that is genuinely the entire description, i'm not gatekeeping anything from you — this one is short and sweet and lowkey does exactly what it says on the tin. it initialises the unicast address list. periodt. 👑

ngl, this page is giving "one-line wonder" energy — but that's fine, because the real drama lives next door in all the sync/flush/add/del functions down in SEE ALSO 🌈
