ksz9477_acl_...h_process_l2(9)

💅 ksz9477_acl_...h_process_l2(9) — kernel API manual, but make it make sense

okay so bestie, this is a page from the Kernel API Manual and the star of the show is ksz9477_acl_match_process_l2. Yes the header on the tin says ksz9477_acl_...h_process_l2(9) but we all know who the main character is 💖

---

✨ NAME ✨

ksz9477_acl_match_process_l2 — sets up Layer 2 ACL matching rules and processing rules. Like, both. At once. She's multitasking. 🎀

---

🌸 SYNOPSIS 🌸

void ksz9477_acl_match_process_l2 (struct ksz_device *dev , int port ,
       u16 ethtype , u8 *src_mac , u8 *dst_mac , unsigned long cookie , u32
       prio );

Returns void, so she gives you nothing back — she just does the thing. No cap. 💅

---

🦋 ARGUMENTS 🦋

Here's the whole squad you gotta pass in, fr fr:

• dev — Pointer to the ksz_device. This is the device herself, the whole vibe. 🫶
• port — Port number. Which port? That one. Int. 🔥
• ethtype — Ethernet type, as a u16. It's giving "what kind of packet are we even talking about". ✨
• src_mac — Source MAC address (u8 *). Where it's coming from, iykyk. 🎀
• dst_mac — Destination MAC address (u8 *). Where it's going. Iconic. 💫
• cookie — The cookie to associate with the entry (unsigned long). Not a real cookie 😭 but okay.
• prio — The priority of the entry (u32). Very important, obviously. 👑

🌈 DESCRIPTION 🌈

So what she actually does: this function sets up matching and processing rules for Layer 2 ACLs. Both halves of the job, one function, slay. 💅

And the one little caveat you must remember, bestie, because it changes how you build your entries:

Only one MAC per entry is supported. One. Single. MAC. Don't come in here trying to fit two. 🙈

That's the whole thing — she's not subtle, she's just specific.

✨ and that's the whole page, bestie ✨ This little gem lives in ./drivers/net/dsa/microchip and it's dated October 2026 — so future-coded of her. Go set those L2 ACL rules, one MAC per entry, and slay. 💖🎀🦋🌸💅👑
