i40e_update_vf_mac_addr(9)

🎀 NAME 🎀

okay bestie, welcome to i40e_update_vf_mac_addr(9) from the Kernel API Manual 💖. The NAME section is literally i40e_update_vf_mac_addr - — yes, with the little dash and no description after it, which is giving mysterious main character energy 💅.

✨ SYNOPSIS ✨

void i40e_update_vf_mac_addr (struct i40e_vf *vf , struct
       virtchnl_ether_addr *vc_ether_addr );

Return type is void, so no return value, no drama, just the function doing its thing 🫶.

🫶 ARGUMENTS 🫶

• vf — the VF to update. Like, that's the target, bestie.
• vc_ether_addr — structure from VIRTCHNL with MAC to add. Literally carries the MAC we're adding ✨.

💖 DESCRIPTION 💖

This one updates the VF's cached hardware MAC if allowed 👑. That “if allowed” is doing a lot of work, so don't gloss over it, iykyk. No extra plot twists in the original — that's the whole description, periodt.

The “if allowed” is not decoration, bestie — it's the whole condition. 💅

🌈 SEE ALSO 🌈

The kernel file is right here, exact path and all: ./drivers/net/ethernet/intel/i40e/i40e_virtchnl_pf.c 🦋.

mwah 💖 that's the whole i40e_update_vf_mac_addr(9) page. The footer source/version is ./drivers/net/ethernet/intel/i40e, the date is October 2026, and yes bestie, that means we're done — bye, love you, no cap 🫶✨
