💖 i40e_client_update_vsi_ctxt(9) 💖

okay bestie, welcome to the Kernel API Manual ✨ this one lives in the i40e driver and it's lowkey a little icon, let's get into it 🫶

---

🌸 NAME 🌸

i40e_client_update_vsi_ctxt — and honestly? the original page gives us nothing after that dash 😭 no one-liner, no vibe description, just the name and a whole lot of silence. so we're just gonna say it: this is the function, bestie, that's the name, that's the whole NAME section 💅

---

🦋 SYNOPSIS 🦋

int i40e_client_update_vsi_ctxt (struct i40e_info *ldev , struct
i40e_client *client , bool is_vf , u32 vf_id , u32 flag , u32 valid_flag
);

look at her go 😭 six whole arguments, she's got range 🔥

---

✨ ARGUMENTS ✨

• ldev — pointer to L2 context. yes queen, hand over the L2 context 👑
• client — the Client pointer. your client, your rules 💅
• is_vf — is this for the VF? like, is this thing a VF or not, that's the question 🧚
• vf_id — if is_vf is true, this is what carries the vf_id 🎀
• flag — any device level setting that needs to be done for PE ⭐
• valid_flag — the bits in this one match up and enable changing of flag bits. so it's giving "permission slip" energy, iykyk 🦋

---

💜 DESCRIPTION 💜

so what does she do? return 0 on success, or < 0 on error 😭 that's it. that's the whole description. no cap, that's literally it — success is 0, error is anything less than 0, and you can take that to the bank 🏦

ngl bestie, don't sleep on that distinction — < 0 covers every error case here, not just your one fave negative number 💀
