💅 sxgbe_check_ether_addr(9) — kernel API manual, bestie edition

okay so this page lives in the Kernel API Manual, and it's literally all about sxgbe_check_ether_addr. pull up a chair 🫶

---

✨ NAME ✨

sxgbe_check_ether_addr — the lil function that checks if the MAC addr is valid 💖

---

🌸 SYNOPSIS 🌸

void sxgbe_check_ether_addr (struct sxgbe_priv_data *priv );

like… that's it. that's the whole signature. no cap. ✨

---

🎀 ARGUMENTS 🎀

• priv — the driver private structure, aka the little bag of everything this driver needs to know about itself 👜 she's the main character of this call, ngl

---

🦋 DESCRIPTION 🦋

so what does she do? her whole job is to verify if the MAC address is valid 👑

and — important part, don't skip this — in case of failures it generates a random MAC address 🎲 like if the check comes back bad, she just makes one up on the spot. girlboss behavior honestly.

💀 reminder bestie: she doesn't fix a bad MAC, she replaces it with a random one. that's the whole bit. don't @ me.
