💌 ixgbe_check_for_msg_pf(9) — the Kernel API Manual, bestie edition

okay so real talk, this is a page straight out of the Kernel API Manual, and it's about ixgbe_check_for_msg_pf — the little function that peeks at the mailbox and is like "did my VF bestie leave me a note?? 👀". Lowkey iconic, highkey essential. Let's get into it.

✨ NAME ✨

ixgbe_check_for_msg_pf — checks to see if the VF has sent mail 💌

like literally it's a mailbox check. the VF slides into your inbox, this function tells you if there's something there. no cap.

🎀 SYNOPSIS 🎀

int ixgbe_check_for_msg_pf (struct ixgbe_hw *hw , u16 vf_number );

that's the whole signature, copy it exactly bestie, don't be weird about the spaces 🫶

🌸 ARGUMENTS 🌸

  • hw — pointer to the HW structure. yes THE hardware struct. the main character. everything goes through her 💅
  • vf_number — the VF index. which VF are we checking on, bestie? gotta know whose mailbox we're snooping 🔍

🦋 DESCRIPTION 🦋

so here's the vibe: this returns SUCCESS if the VF has set the Status bit, or else ERR_MBX. that's it. that's the whole function. it's giving "short and sweet, knows exactly what she's about" 💀

status bit set → SUCCESS slay ✨ status bit not set → ERR_MBX, no mail for you 🙈

🔥 SEE ALSO 🔥

the kernel file it lives in, fr fr:

./drivers/net/ethernet/intel/ixgbe/ixgbe_mbx.c

and the whole mailbox friend group — go read these too, they're all linked:

ok that's the whole page!! go check your mailboxes babes, and remember: status bit set = SUCCESS, otherwise ERR_MBX. periodt 💜

this cutie was served up from ./drivers/net/ethernet/intel/i... (the source/version line, truncated by the man page itself, not by me 🥲), dated October 2026 — and that's the ixgbe_check_for_msg_pf(9) footer, now with 100% more sparkle 🌈⭐🎀
