i40e_set_vsi_promisc(9)

💅 i40e_set_vsi_promisc(9) — NAME

okay so bestie, welcome to the Kernel API Manual ✨ this page is literally about i40e_set_vsi_promisc and — not gonna lie — the official one-liner is completely blank 😭 like the NAME section is just a dash and nothing else. So we're all just out here vibing with a mystery function. Slay, I guess 💀

---

✨ SYNOPSIS ✨

int i40e_set_vsi_promisc (struct i40e_vf *vf , u16 seid , bool
       multi_enable , bool unicast_enable , s16 *vl , u16 num_vlans );

that's the whole vibe. six args, one int coming back at you 🫶

---

🎀 ARGUMENTS 🎀

okay this is the part where you actually read, bestie, I believe in you 💖

• vf — pointer to the VF struct 🌸 that's it, that's the whole note.
• seid — the VSI number 🦋 your very own VSI id, iconic.
• multi_enable — set MAC L2 layer multicast promiscuous enable/disable for a given VLAN 👑 yes, both directions with one flag, we love a multitasker.
• unicast_enable — set MAC L2 layer unicast promiscuous enable/disable for a given VLAN 🌈 same deal, another on/off situation.
• vl — List of VLANs — apply filter for given VLANs 🍓 it's a s16 *, so it's a list, not a single lonely VLAN.
• num_vlans — Number of elements in vl ⭐ like, the count. the length. the how-many. don't get these two confused or it's giving undefined chaos 💀

fr fr: vl and num_vlans are a package deal — one's the list, one's the length. treat them as a matching set 🫶

okay that's the whole page and you ate that 💅 this beauty came out of the ./drivers/net/ethernet/intel/i40e directory, dropped in October 2026, and lives proudly in section 9 of the manual — go forth and set some promiscuous filters, queen 👑💖
