pch_gbe_set_mac(9)

🎀 NAME 🎀

okay so bestie, this is the pch_gbe_set_mac(9) page from the Kernel API Manual, and the whole mission is literally this: pch_gbe_set_mac — Change the Ethernet Address of the NIC. that's the name, that's the assignment, periodt. ✨💅

---

💅 SYNOPSIS 💅

the signature is <highkey>exactly</highkey> this, no cap:

int pch_gbe_set_mac (struct net_device *netdev , void *addr );

---

🦋 ARGUMENTS 🦋

two args walk into a function, and yes they both matter:

• netdev — Network interface device structure. it's giving “the NIC's whole identity” energy.
• addr — Pointer to an address structure. that's where the address situation lives. 🫶

---

🌸 RETURN 🌸

the return vibe check is:

• 0: Successfully
• -EADDRNOTAVAIL: Failed

so yeah: 0 is slay, -EADDRNOTAVAIL is not slay. 💀✨
