Kernel API Manual page for idpf_send_en...loopback_msg(9) — the header shows it short and cute like that, while the NAME says the full idpf_send_ena_dis_loopback_msg. Bestie, this is the group-chat recap of the function that sends a virtchnl enable/disable loopback message 💅✨

🌸 NAME 🌸

idpf_send_ena_dis_loopback_msg — Send virtchnl enable/disable loopback message.

🛠️ SYNOPSIS 🛠️

int idpf_send_ena_dis_loopback_msg (struct idpf_adapter *adapter , u32
       vport_id , bool loopback_ena );

🎀 ARGUMENTS 🎀

• adapter — adapter pointer used to send virtchnl message.
• vport_id — vport identifier used while preparing the virtchnl message.
• loopback_ena — flag to enable or disable loopback.

✨ RETURN ✨

0 on success, negative on failure. That's the whole mood, no cap.
