💅 idpf_send_set_rss_key_msg — bestie's guide to the kernel API manual ✨

okay so real quick context before we dive in: this is a page from the Linux kernel API manual, and the star of the show is idpf_send_set_rss_key_msg. That's the whole vibe. 🫶

✨ NAME ✨

idpf_send_set_rss_key_msg — literally just sending the virtchnl set RSS key message. that's it. that's the whole job. no cap. 💅

🌸 SYNOPSIS 🌸

int idpf_send_set_rss_key_msg (struct idpf_adapter *adapter , struct
       idpf_rss_data *rss_data , u32 vport_id );

three args, one int coming back at you. slay.

🎀 ARGUMENTS 🎀

  • adapter — the adapter pointer, aka the little messenger you use to actually send the virtchnl message. it's giving "delivery service." 📦
  • rss_data — pointer to the RSS key and lut info. two things, one pointer, highkey efficient. 🦋
  • vport_id — the vport identifier, used while preparing the virtchnl message. it's how the message knows which vport it belongs to, iykyk. 👑

💖 RETURN 💖

  • 0 on success 🎉
  • negative on failure 😭
bestie the vibes are: zero means we ate, negative means we did not eat. check it every time, fr fr.

🧚 SEE ALSO 🧚

okay this list is LONG and honestly iconic — it's the whole idpf friend group. every single one of them, in order, no skipping, because we do not do that here 💜

also, the kernel file itself lives at ./drivers/net/ethernet/intel/idpf/idpf_virtchnl.c — go say hi. 🌈

that's the page bestie, go send your virtchnl messages responsibly 💅✨
