i40e_aq_add_veb(9)

✨ i40e_aq_add_veb ✨

okay so bestie, we're deep in the Kernel API Manual today, and the star of the show is i40e_aq_add_veb(9) — the function that's literally matchmaking a VEB between your VSI and your MAC. networking wingman energy fr fr 💅

🌸 NAME 🌸

i40e_aq_add_veb — Insert a VEB between the VSI and the MAC

---

🎀 SYNOPSIS 🎀

int i40e_aq_add_veb (struct i40e_hw *hw , u16 uplink_seid , u16
downlink_seid , u8 enabled_tc , bool default_port , u16 *veb_seid , bool
enable_stats , struct i40e_asq_cmd_details *cmd_details );

---

🦋 ARGUMENTS 🦋

• hw — pointer to the hw struct. your main character struct, the one you pass to literally everything.
• uplink_seid — the MAC or other gizmo SEID. yes, "gizmo" is doing canonically the technical work here 😭
• downlink_seid — the VSI SEID
• enabled_tc — bitmap of TCs to be enabled
• default_port — true for default port VSI, false for control port
• veb_seid — pointer to where to put the resulting VEB SEID. it's an out-param bestie, give it somewhere to live 🫶
• enable_stats — true to turn on VEB stats
• cmd_details — pointer to command details structure or NULL

---

💖 DESCRIPTION 💖

So the way this works is — you're asking the FW (firmware, the other boss here) to add a VEB between the uplink and downlink elements. that's it, that's the whole vibe: uplink on one side, downlink on the other, VEB in the middle. matchmaker, matchmaker, make me a match 💫

And here's the cute little plot twist: if the uplink SEID is 0, this will be a floating VEB. no cap. zero means float. 🎈
