i40e_is_vc_addr_primary(9)

📦 version 7.3.1, in nixpkgs unstable

🌸 i40e_is_vc_addr_primary 💅

okay so bestie, welcome to i40e_is_vc_addr_primary(9) — a page from the Kernel API Manual, and yes the NAME section is literally just the function name with nothing after it, she's mysterious like that, we love a lowkey entrance. ✨

🌈 SYNOPSIS

bool i40e_is_vc_addr_primary (struct virtchnl_ether_addr *vc_ether_addr
);

it returns a bool, she takes exactly one pointer, and that's the whole vibe check. 🫶

🎀 ARGUMENTS

  • vc_ether_addr — a VIRTCHNL structure that contains MAC and type. that's it, that's the parameter. she's carrying the MAC and the type and honestly she's doing great. 💖

🦋 DESCRIPTION

so what does she actually do? she checks if the MAC address is the VF's primary MAC. iconic behavior, no notes. 👑

⚠️ okay this part is important and i need you to actually read it: this function should only be called when the MAC address in virtchnl_ether_addr is a valid unicast MAC. like, that's the whole precondition. don't come for her with a non-valid-unicast MAC, she's not built for that and it's not the vibe. 😭

⭐ SEE ALSO

she has a lot of friends, and i mean a lot — this is the group chat and everyone's in it:

the source file (iykyk):

  • Kernel file ./drivers/net/ethernet/intel/i40e/i40e_virtchnl_pf.c

and the whole squad:

like i said. everyone. 🫶💀

and that's the whole page bestie, short and slay 💅 — this iconic little doc lives in ./drivers/net/ethernet/intel/i40e, dated October 2026, and no fr this page is literally titled i40e_is_vc_addr_primary(9) at the top and bottom because she's nothing if not consistent. 🎀✨🌸
