irdma_get_vlan_mac_ipv6(9)

💅 irdma_get_vlan_mac_ipv6 — like, the vlan AND the mac, bestie ✨

okay so real talk: this is a page from the Kernel API Manual, section 9 — irdma_get_vlan_mac_ipv6(9). Yes the title is a mouthful, no I will not be shortening it, it's iconic and we respect it 🫶

---

🌸 NAME 🌸

irdma_get_vlan_mac_ipv6 — gets the vlan and mac. that's it. that's the whole job. no cap 💅

---

🦋 SYNOPSIS 🦋

void irdma_get_vlan_mac_ipv6 (u32 *addr , u16 *vlan_id , u8 *mac );

literally just three pointers in, nothing out — the function is void, she returns nothing, she just does things. main character energy fr 🔥

---

🎀 ARGUMENTS 🎀

• addr — the local IPv6 address. yes it's a u32 *, don't ask, just pass it 💖
• vlan_id — the vlan id for the given IPv6 address. she's a u16 *, she holds the vlan number 🍓
• mac — the mac address for the given IPv6 address. u8 *, and this is where the hardware address lands ✨

---

🌈 DESCRIPTION 🌈

Returns the vlan id and mac for an IPv6 address. that's the whole description, bestie — short, sweet, and absolutely not here to waste your time 👑

heads up: all three of those args are pointers, so like… bestie, please make sure they're valid before you call. the page doesn't hold your hand and neither will I 🙈
