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

okay so we're in the ice section of the Kernel API Manual and today's main character is ice_cfg_mac_antispoof, a little function with a big job. no cap, it's giving "quietly keeps the network honest" energy. 🦋

✨ NAME ✨

ice_cfg_mac_antispoof — configure MAC antispoof checking behavior

like, it's the switch-flipper for whether a VSI gets to pretend to be a MAC address it is not. rude behavior, honestly. 🙈

---

🌸 SYNOPSIS 🌸

int ice_cfg_mac_antispoof (struct ice_vsi *vsi , bool enable );

that's it. that's the whole vibe. two arguments, one int coming back at you. 🎀

---

💖 ARGUMENTS 💖

• vsi — the VSI to configure. literally the thing you're doing the configuring to, bestie. it's the star of the show. ⭐
• enable — whether to enable or disable the spoof checking. true-ish = checking is ON, the other one = checking is OFF. you're the DJ of spoof checking. 🎧

---

👑 DESCRIPTION 👑

Configure a VSI to enable (or disable) spoof checking behavior.

that's the whole plot, and honestly? it ate. you point it at a VSI, you tell it enable, and the spoof checking behavior is now configured. periodt. 💅 no secret twist, no hidden lore, the function does exactly what the name says, which is honestly iconic of it.

lowkey a slay that a kernel function is this straightforward. not every icon needs a 40-line description. 🫶

fr fr if you're reading this page you should probably also go read ice_vsi_ena_spoofchk(9) and ice_vsi_dis_spoofchk(9) and ice_vsi_apply_spoofchk(9) — they're right there in the list, and they're literally the spoof-checking trio. iykyk. ✨

and that's the page, bestie!! go forth and configure your MAC antispoof checking behavior responsibly 💜
