💌 ixgbevf_read_mbx_vf — the kernel API page, but make it make sense

okay so bestie, welcome to ixgbevf_read_mbx_vf(9) — yes that's the manual page name and the function name, she's got main character energy like that 💅. This is a page from the Kernel API Manual, and it's literally all about pulling a message out of the inbox that was meant for the VF. Let's get into it 🎀

✨ NAME ✨

ixgbevf_read_mbx_vf — reads a message from the inbox intended for VF 🦋

like... that's the whole gig. she reads. she receives. she slays.

🌸 SYNOPSIS 🌸

s32 ixgbevf_read_mbx_vf (struct ixgbe_hw *hw , u32 *msg , u16 size );

that's the signature, copy it exactly bestie, don't be cute with it 😭

🎀 ARGUMENTS 🎀

  • hw — pointer to the HW structure 💖 lowkey the hardware brain you're handing over
  • msg — the message buffer 📨 this is where the good stuff lands
  • size — length of buffer 📏 yes, size matters, that's the whole point of the parameter

⭐ DESCRIPTION ⭐

returns 0 if it successfully read message from buffer ✨

that's it. that's the description. zero means we ate, anything else means the vibe check failed 🙈

🦋 SEE ALSO 🦋

first up, the actual source file, sitting pretty at:

  • Kernel file ./drivers/net/ethernet/intel/ixgbevf/mbx.c

and then the whole friend group — every single one of these, no skipping 👑

ngl bestie, the "*_legacy" ones are right there in the list, so go look at them if you need them — I'm not out here inventing lore 💀

and that's the page!! 🫶 the source path at the bottom is ./drivers/net/ethernet/intel/i... (truncated, tragic, she ran out of room 😭) and the date stamp says October 2026, so yeah — this lil doc is dated October 2026 and it's brought to you by the same manual that titles itself ixgbevf_read_mbx_vf(9) in the footer too. periodt. 🍓🧚💜
