🎀 NAME 🎀

alb_set_mac_address - (the description slot is literally empty here, so… blank vibes 🫥)

---

🌸 SYNOPSIS 🌸

int alb_set_mac_address (struct bonding *bond , void *addr );

---

🫶 ARGUMENTS 🫶

• bond — bonding we're working on (yes, that bonding, bestie 💅)
• addr — MAC address to set

---

✨ DESCRIPTION ✨

okay so in TLB mode, all slaves are configured to the bond's hw address, but they set their dev_addr field to different addresses — and those different addresses are based on their permanent hw addresses 🌈.

For each slave, this function sets the interface to the new address and then changes its dev_addr field to its previous value. Like, new address on the interface, then dev_addr goes back to the old value 🫶.

⚠️ unwinding caveat: unwinding assumes the bond's mac address has not yet changed. That's the assumption, bestie — keep it in mind, fr fr.
