iavf_add_filter(9)

💅 iavf_add_filter(9) — adding a MAC filter to the filter list ✨

okay so this one lives in the Kernel API Manual, section 9, and it's genuinely one of the smaller little guys in the iavf family but it's still doing important work, bestie 🫶

---

🌸 NAME 🌸

iavf_add_filter — literally just: add a mac filter to the filter list 💖

---

🦋 SYNOPSIS 🦋

struct iavf_mac_filter * iavf_add_filter (struct iavf_adapter *adapter ,
const u8 *macaddr );

---

🎀 ARGUMENTS 🎀

• adapter — the board private structure 👑 (yes that's the whole description, she's lowkey mysterious like that)
• macaddr — the MAC address 💅

---

⭐ DESCRIPTION ⭐

Returns a ptr to the filter object, or NULL when no memory is available 😭 no cap, that's the entire description. check the return value, bestie, i'm begging 🙈

tiny function, huge "please handle the NULL" energy 💀
