fm10k_tlv_attr_put_mac_vlan(9)

💅 fm10k_tlv_attr_put_mac_vlan — NAME 🌸

okay so bestie, welcome to the Kernel API Manual — this one's about fm10k_tlv_attr_put_mac_vlan, which (deep breath, it's giving very descriptive) stores a MAC/VLAN attribute in a message. that's it. that's the whole vibe. 💖

---

✨ SYNOPSIS ✨

s32 fm10k_tlv_attr_put_mac_vlan (u32 *msg , u16 attr_id , const u8
*mac_addr , u16 vlan );

like, she takes four things and returns a s32. main character signature, honestly. 🎀

---

🫶 ARGUMENTS 🫶

• msg — pointer to the message block 🦋
• attr_id — the attribute ID, i.e. her little name tag
• mac_addr — the MAC address that's gonna get stored
• vlan — the VLAN that's gonna get stored

no cap, that's all four. slay. 💅

---

🌈 DESCRIPTION 🌈

so what she actually does: this function reorders the MAC address to be CPU endian and then stores it in the attribute buffer. she's out here fixing your byte order for you, lowkey iconic behavior tbh. 🔥

and she'll return success if provided with valid pointers — so like, give her good pointers and she's happy. give her nonsense and, well, that's on you bestie. 😭

fr fr though: valid pointers are the whole deal here. that's the contract. don't be weird about it. 💀
