💅 __iavf_maybe_stop_tx(9) 💅

okay bestie, we're in the Kernel API Manual and this page is literally about the 2nd level check for tx stop conditions ✨ it's giving very specific networking internals and we're gonna get through it together, no cap 🫶

✨ NAME ✨

__iavf_maybe_stop_tx — the 2nd level check for tx stop conditions, periodt 💅

🦋 SYNOPSIS 🦋

int __iavf_maybe_stop_tx (struct iavf_ring *tx_ring , int size );

🎀 ARGUMENTS 🎀

• tx_ring — the ring to be checked 👑
• size — the size buffer we want to assure is available 🌸

💖 DESCRIPTION 💖

Return vibe check: it returns -EBUSY if a stop is needed, else 0. That's the whole little lore drop, bestie 😭
