ksz9477_acl_write_list(9)

💅 ksz9477_acl_write_list(9) — the Kernel API Manual glow-up 🎀

okay so bestie, you found ksz9477_acl_write_list in the Kernel API Manual and I'm literally obsessed, because this lil function is the one that actually pushes your whole ACL list out to a port. no cap. let's get into it ✨

---

🌸 NAME 🌸

ksz9477_acl_write_list — write a list of ACL entries to a given port. that's it, that's the gig 💅

---

🦋 SYNOPSIS 🦋

int ksz9477_acl_write_list (struct ksz_device *dev , int port );

---

🎀 ARGUMENTS 🎀

• dev — the ksz_device instance. your main character struct fr fr 🫶
• port — the port number on which to write ACL entries. like, which port is getting the makeover 💁‍♀️

---

✨ DESCRIPTION ✨

so here's the vibe: this function enables ACL functionality on the specified port, writes a list of ACL entries to the port, and then — and this is the detail I need you to remember — disables ACL functionality if there are no entries. so it's giving "turn the lights on, do the thing, turn the lights back off if nobody showed up." iconic behavior honestly 🔥

---

💖 RETURN 💖

0 if the operation is successful, or a negative error code if an error occurs. so like, zero means slay, negative means 😭.
