ice_vc_request_qs_msg(9)

✨ NAME ✨

ice_vc_request_qs_msg — bestie, the NAME section is giving minimalism: it’s just the function name, no extra tagline. This page is from the Kernel API Manual, and we’re about to get into it. 🫶

🦋 SYNOPSIS 🦋

int ice_vc_request_qs_msg (struct ice_vf *vf , u8 *msg );

🎀 ARGUMENTS 🎀

• vf — pointer to the VF info. literally the VF info pointer.
• msg — pointer to the msg buffer. yep, a pointer to the message buffer.

💅 DESCRIPTION 💅

okay so VFs get a default number of queues, but they can use this message to request a different number. lowkey the whole point. 🔥

if the request is successful, the PF will reset the VF and return 0. slay. if the request is unsuccessful, the PF will send a message informing the VF of the number of available queue pairs via a virtchnl message response to the VF. no cap, that’s the flow. 💖
