ixgbe_vf_handle_tx_hang(9)

📦 version 7.3.1, in nixpkgs unstable

💅 ixgbe_vf_handle_tx_hang(9) — the Kernel API Manual page your bestie actually wants to read

okay so. this is a page straight out of the Kernel API Manual (section 9, iykyk), and it's about one very specific little function that handles a very specific little situation. let's get into it 🫶

✨ NAME ✨

ixgbe_vf_handle_tx_hang — handle Tx hang on VF

like, literally what it says on the tin. a VF's Tx went sideways and this is the girl they call 💅

🌸 SYNOPSIS 🌸

void ixgbe_vf_handle_tx_hang (struct ixgbe_adapter *adapter , u16 vf );

no return value, bestie. it just does the thing and goes home. returns void. iconic behavior honestly ✨

🎀 ARGUMENTS 🎀

  • adapter — the structure containing ring specific data. this is where all the good stuff lives 💖
  • vf — the VF index. which virtual function we're talking about, basically the little number that says "her. that one. 👀"

🦋 DESCRIPTION 🦋

okay so here's the vibe:

it prints a message containing details about malicious driver detection. yes, malicious. we're snitching on a bad driver, in writing, with details 📝🔥

and if that detection happened several times? it sets the malicious VF link down. like — ma'am, you've been caught multiple times, the link is going down, no cap. 🚫💀 that's not a warning, that's a consequence, fr fr.

so tl;dr: detect the sketchy behavior, announce it loudly, and if it keeps happening, take the link down. rude? maybe. correct? absolutely. 💅

🌈 SEE ALSO 🌈

first up, the actual kernel file this lives in, because you know you're gonna want to read the source:

  • Kernel file ./drivers/net/ethernet/intel/ixgbe/ixgbe_main.c

and now the full friend group — every single one, no skipping, because we don't do that here 👑:

like, that's the whole extended universe bestie. 118 of them. we did not skip a single one and we are NOT going to 😤💖

okay that's the page!! this one came from the source path ./drivers/net/ethernet/intel/i... and it's dated October 2026, so bookmark it, screenshot it, send it to the group chat — mwah, love u, bye 🧚‍♀️🎀💜
