💅 ksz9477_port_acl_init(9) — Kernel API Manual 🎀

okay bestie, so this one is a <pink>Kernel API Manual</pink> page and honestly it's giving "small function, big responsibilities." Strap in 🦋

---

✨ NAME ✨

ksz9477_port_acl_init — literally the function that initializes the ACL for a specified port on a ksz device. that's it, that's the whole vibe 💅

---

🌸 SYNOPSIS 🌸

int ksz9477_port_acl_init (struct ksz_device *dev , int port );

---

🎀 ARGUMENTS 🎀

• dev — the ksz_device instance. yes, that one, the device struct, hand it over 🫶
• port — the port number you wanna initialize the ACL for. like, this port specifically 👑

---

💖 DESCRIPTION 💖

so here's the tea ☕ — this function allocates memory for an acl structure, associates it with the specified port, and initializes the ACL entries to a default state. three steps, one little function, main character energy for real 🔥

the entries then get written out using the ksz9477_acl_write_list function — which is the whole point, because that's what ensures the ACL has a predictable initial hardware state. no chaos, no surprises, just a clean starting line ✨ ngl that's kind of iconic of it.

---

⭐ RETURN ⭐

0 on success, or an error code on failure. so like, 0 = slay, anything else = go check what went wrong 😭
