bnx2x_validate_vlan_mac_add(9)

💅 bnx2x_validate_vlan_mac_add(9) — bestie's guide to the Kernel API Manual

okay so this is a page from the Kernel API Manual, and it's honestly giving "tiny function, big responsibilities." we're talking about bnx2x_validate_vlan_mac_add, and yes she's a mouthful, but she's also the vibe check for VLAN/MAC ADD commands. let's get into it 🎀

---

✨ NAME ✨

bnx2x_validate_vlan_mac_add — the girl who checks if an ADD command can actually be executed 💅

---

🌸 SYNOPSIS 🌸

int bnx2x_validate_vlan_mac_add (struct bnx2x *bp , union
       bnx2x_qable_obj *qo , struct bnx2x_exeq_elem *elem );

that's it, that's the whole signature. three args, one int, no cap 🔥

---

🦋 ARGUMENTS 🦋

• bp — the device handle. like, which device are we even talking to, bestie
• qo — a bnx2x_qable_obj. yes that's the actual type name, i don't make the rules
• elem — a bnx2x_exeq_elem. the element in question, the main character of this operation 💫

---

👑 DESCRIPTION 👑

so what does she do? she checks that the requested configuration can be added. that's the whole job. 🫶

and here's the slay part: if the answer is yes, and if it was requested, she consumes CAM credit. iconic. budget-conscious queen 💸

🧚 important lore: the 'validate' is run after the 'optimize'. order matters, bestie, don't come for me 💀
