idpf_del_mac_filter(9)

💅 idpf_del_mac_filter — a Kernel API Manual moment

okay so bestie, we're in the Kernel API Manual today and the function we're stanning is idpf_del_mac_filter. yes it's giving "delete a MAC filter from the filter list" and yes it's exactly as iconic as it sounds. let's get into it 🎀

---

✨ NAME ✨

idpf_del_mac_filter — delete a MAC filter from the filter list. that's it, that's the whole job, and she does it flawlessly 💅

---

🌸 SYNOPSIS 🌸

int idpf_del_mac_filter (struct idpf_vport *vport , struct
idpf_netdev_priv *np , const u8 *macaddr , bool async );

literally just look at her. returns an int, takes four things, no drama. 🦋

---

🎀 ARGUMENTS 🎀

• vport — the main vport structure. main character energy fr, she runs the whole vport situation.
• np — the netdev private structure. the little private stash of netdev secrets 🙈
• macaddr — the MAC address. the actual address in question, the one getting filtered.
• async — don't wait for the return message. so when this is set, we're not sticking around for the reply — it's giving "sent, bye, not waiting" 💀

---

🔥 DESCRIPTION 🔥

so what does she do? two things, and she does them both:

1. removes the filter from the list — gone, deleted, not on the list anymore ✨
2. and if the interface is up, she tells the hardware all about the filter that just got removed 👑

no cap, that's the whole flow. list first, hardware after — but only when the interface is up. iykyk 🌈
