ksz9477_port_acl_free(9)

💅 ksz9477_port_acl_free(9) — the Kernel API Manual glow-up ✨

okay so bestie, we're in the Kernel API Manual today and this little function is genuinely iconic. it's called ksz9477_port_acl_free and it lives in the kernel docs, so you KNOW it's doing main character work 🌸

---

✨ NAME ✨

ksz9477_port_acl_free — frees the ACL resources for a specified port on a ksz device 🎀

like, it's the cleanup era. the goodbye era. the "we're done here, release the memory" era 💅

---

🦋 SYNOPSIS 🦋

void ksz9477_port_acl_free (struct ksz_device *dev , int port );

yup, that's the whole vibe check — a void return, so it doesn't hand anything back to you, it just does the thing. no notes. periodt ✨

---

🌸 ARGUMENTS 🌸

• dev — the ksz_device instance. this is your main character struct, the device we're operating on 🫶
• port — the port number to initialize the ACL for. yes, the original docs literally say "initialize" here even though this is the free function — that's what it says, so that's what we're telling you, ngl 😭

---

💖 DESCRIPTION 💖

so what does it actually do? okay so:

this disables the ACL for the specified port and frees the associated memory 💀

that's it. that's the whole function. it turns the ACL off for that port and then lets the memory go. lowkey the most satisfying kind of kernel function — the one that cleans up after everybody else 🔥

bestie note: this is a cleanup function, so think about it like closing the group chat after the plans are made. no ACL, no memory, no drama 🧚
