ice_vc_repr_add_mac(9)

💅 ice_vc_repr_add_mac(9) 💅

a Kernel API Manual moment, bestie ✨

okay so before we even get into it — this page lives in the Kernel API Manual, section 9, and it's about one very specific little function. buckle up, it's a short one but it's iconic 🎀

---

✨ NAME ✨

ice_vc_repr_add_mac —

and like… that's it. the description line is literally empty. no cap, the manpage just drops the name and ghosts us 💀 the actual tea is in DESCRIPTION, keep scrolling.

---

🌸 SYNOPSIS 🌸

int ice_vc_repr_add_mac (struct ice_vf *vf , u8 *msg );

so it takes two things and hands you back an int, periodt 💅

---

🦋 ARGUMENTS 🦋

• vf — pointer to VF 🫶 (yes, that's the whole description. pointer. to a VF. short and sweet.)
• msg — virtchannel message ✨ (the message that came in over the virtchannel)

---

💖 DESCRIPTION 💖

okay so here's the situation, bestie — when port representors get created, we do not add the MAC rule to firmware. like, at all. nope 🙈

instead we store it, so that the PF can report the same MAC as the VF. that's the whole vibe. that's the function. storing it is the main character energy here 👑

no firmware writes happening on this path — just a little storage moment so PF and VF stay matching. 🧚
