bdx_tx_space(9)

📦 version 7.3.1, in nixpkgs unstable

💅 bdx_tx_space(9) — like, the Kernel API Manual, bestie ✨

okay so real talk, this is a man page from the <pink>Kernel API Manual</pink> — section 9, the whole thing is called bdx_tx_space(9), and it's literally one little function that tells you how much room you've got left in the TX fifo 🎀 no cap, that's the whole vibe.

🌸 NAME 🌸

bdx_tx_space — bestie, it calculates available space in TX fifo 💖

✨ SYNOPSIS ✨

int bdx_tx_space (struct bdx_priv *priv );

that's it. that's the whole call. one arg, returns an int, we love a low-maintenance icon 👑

🦋 ARGUMENTS 🦋

  • priv — the NIC private structure 🫶 like, the network interface card's own little private struct, it's giving main character energy, it holds all the deets

🍓 DESCRIPTION 🍓

Okay so what does it do? It returns available space in TX fifo in bytes ✨ that's it. that's the whole function. how many bytes can you still shove into the transmit fifo before it's full, that's the answer it gives you back 💅

fr fr, that's the entire description. no extra lore, no secret side quests. the man page said what it said and I'm not gonna invent fanfiction about it 🙈

🔥 SEE ALSO 🔥

okay this is the part where it gets long, but we do not skip, we list every single one because we're thorough like that 💜 the kernel file this all lives in is ./drivers/net/ethernet/tehuti/tehuti.c and here's the whole friend group:

that's thirty whole entries, we counted, we did not skip a single one 🧚 iykyk 🌈

and that's the whole page, bestie 😭💖 it's short, it's sweet, it's a one-liner with a thirty-entry friend list, iconic behaviour honestly 🎀

this beauty comes to you from ./drivers/net/ethernet/tehuti, dated <lavender>October 2026</lavender> — mwah, love u, go check your fifo space 💅✨🦋
