ice_vc_send_msg_to_vf(9)

📦 version 7.3.1, in nixpkgs unstable

💌 ice_vc_send_msg_to_vf — a Kernel API Manual moment (yes, it's a (9) section page, we're fancy)

okay so bestie, welcome to the little corner of the kernel where the PF (that's the physical function, the boss vibes) slides a message over to a VF. This page lives in the Kernel API Manual, section 9, and it's literally just one function doing one job. Let's get into it 🫶

✨ NAME ✨

ice_vc_send_msg_to_vf — Send message to VF

like, that's it. that's the whole pitch. no cap 💅

🌸 SYNOPSIS 🌸

int ice_vc_send_msg_to_vf (struct ice_vf *vf , u32 v_opcode , enum
       virtchnl_status_code v_retval , u8 *msg , u16 msglen );

she takes five args and gives you back an int. icon behavior ✨

🦋 ARGUMENTS 🦋

okay so here's what each of these cuties actually is:

  • vf — pointer to the VF info. this is the whole reason we're here, bestie 🎀
  • v_opcode — virtual channel opcode
  • v_retval — virtual channel return value
  • msg — pointer to the msg buffer
  • msglen — msg length

periodt. those are the five. 💜

👑 DESCRIPTION 👑

send msg to VF

that's the entire description 💀 the kernel devs really said "brevity is a personality" and honestly? respect. she stays in her lane. main character energy.

🔥 SEE ALSO 🔥

the friend group is enormous, ngl. gather round, this is the whole gc:

Kernel file ./drivers/net/ethernet/intel/ice/virt/virtchnl.c

seventy-one entries. seventy-ONE. not me counting 💀 but like, slay, she's connected. iykyk 🧚

real talk though bestie: every single one of those (9) suffixes means "this is a kernel API page too", so if you're ever lost, just man 9 your way through the list. the manual is your friend fr fr 🫶

🎀 sign-off 🎀

that's the page! source/version line reads ./drivers/net/ethernet/intel/i... (they truncated it on us, tragic) and it's dated October 2026 — and yes, the footer still says ice_vc_send_msg_to_vf(9) because she's consistent like that. go send some messages to your VFs, bestie, you got this 💅✨🌸
