i40e_aq_query_vsi_bw_config(9)

💅 i40e_aq_query_vsi_bw_config(9) — like, the whole vibe check on VSI bandwidth config 🎀

okay bestie, so this is a page from the Kernel API Manual (section 9, the kernel-functions one, iykyk) and it's about i40e_aq_query_vsi_bw_config — a function living in the i40e driver. it's basically the "hey firmware, what's the bandwidth setup on this VSI?" call. no cap, that's the whole plot 💖

---

✨ NAME ✨

i40e_aq_query_vsi_bw_config — Query VSI BW configuration. that's it, that's the name, go off 👑

---

🌸 SYNOPSIS 🌸

so here's the exact signature, character for character, don't @ me:

int i40e_aq_query_vsi_bw_config (struct i40e_hw *hw , u16 seid , struct
i40e_aqc_query_vsi_bw_config_resp *bw_data , struct i40e_asq_cmd_details
*cmd_details );

it returns an int (obvi) — and yes, it takes four things. we'll get to those 🫶

---

🦋 ARGUMENTS 🦋

listen, arguments are where manpages usually get boring. not today. not on my watch 💅

• hw — pointer to the hw struct. your hardware handle, your main character. everything goes through it ✨
• seid — a u16, the seid of the VSI. that's the ID of the VSI you're asking about, so firmware knows which one you mean 🎀
• bw_data — Buffer to hold VSI BW configuration. this is where the answer lands when it comes back, so like… make sure it's real memory, bestie 🙈 (type: struct i40e_aqc_query_vsi_bw_config_resp *)
• cmd_details — pointer to command details structure, or NULL. literally your choice. NULL is fine, it's giving low-maintenance 🍓 (type: struct i40e_asq_cmd_details *)

like?? that's the entire extended universe. every single one is in section 9. periodt 💀

ngl, the manpage doesn't spell out return values or error codes here, so i'm not gonna invent any — we only ship facts on this page, bestie 🫶
