i40e_client_virtchnl_send(9)

💅 i40e_client_virtchnl_send(9)

okay bestie, so this is a page straight out of the Kernel API Manual, and it's about i40e_client_virtchnl_send(9). yes it's a mouthful. yes we're gonna get through it together. 🫶

✨ NAME ✨

i40e_client_virtchnl_send — so the official manpage literally says TBD here. that's it. that's the description. not me making it up, the kernel devs left us on read. 💀 iconic behaviour honestly, we respect the mystery.

🦋 SYNOPSIS 🦋

int i40e_client_virtchnl_send (struct i40e_info *ldev , struct
i40e_client *client , u32 vf_id , u8 *msg , u16 len );

like, look at that signature. returns an int, takes five args, no notes. she's got main character energy and a very long parameter list. 👑

🎀 ARGUMENTS 🎀

here's the whole squad, no one left behind:

• ldev — pointer to L2 context. that's her. the L2 context connection.
• client — Client pointer. yes the capitalization is theirs, we're not touching it. 😌
• vf_id — absolute VF identifier. absolute. no vibes-based relative IDs here, it's the real one. 🔥
• msg — message buffer. this is where the message lives. carrying the message, lowkey a messenger.
• len — length of message buffer. the msg and the len are a matched set, iykyk. 🧚

🌸 DESCRIPTION 🌸

the entire description, verbatim in spirit: Return 0 on success or < 0 on error.

that's it. that's the whole lore. 0 = we ate, negative = something went sideways. periodt. ✨
