✨ wx_write_uc_addr_list(9) ✨

okay so bestie, welcome to the Kernel API Manual — we're doing a wx_write_uc_addr_list(9) deep dive today and honestly? it's a good one. grab a snack 🍓

---

💖 NAME 💖

wx_write_uc_addr_list — write unicast addresses to RAR table

no cap, that's literally the whole vibe: unicast addresses go in, RAR table comes out. slay.

---

🎀 SYNOPSIS 🎀

int wx_write_uc_addr_list (struct net_device *netdev , int pool );

that's it. two args, one int coming back at you. main character energy fr fr.

---

🦋 ARGUMENTS 🦋

• netdev — the network interface device structure 👑 like, the whole device, the entire moment
• pool — the index for the mac table 🗂️ which table we're writing into, iykyk

---

🌸 DESCRIPTION 🌸

Writes the unicast address list to the RAR table. that's the whole thing. it's giving "short and iconic" ✨

---

🌈 RETURN 🌈

okay bestie, the return value is doing multiple jobs, so pay attention 💅

• -ENOMEM — on failure / insufficient address space 😭 (not enough room, she's full)
• 0 — on no addresses written 🙈 (nothing to do, we ball)
• X — on writing X addresses to the RAR table 🔥 (yes, the return value is the count, she's counting)
