stmmac_configure_cbs(9)

💅 stmmac_configure_cbs — the stmmac_configure_cbs(9) glow-up

okay so this is a page from the Kernel API Manual, bestie — specifically the stmmac_configure_cbs(9) entry. it's short, it's sweet, and it does exactly one (1) thing. let's get into it ✨

---

🌸 NAME 🌸

stmmac_configure_cbs — configure CBS in TX queue

like, that's it. that's the whole name. CBS goes in the TX queue. slay.

---

🦋 SYNOPSIS 🦋

void stmmac_configure_cbs (struct stmmac_priv *priv );

no return value, no drama, just vibes and a pointer. 💅

---

🎀 ARGUMENTS 🎀

• priv — the driver private structure. that's your whole personality right there, fr fr.

---

✨ DESCRIPTION ✨

so what does it do? it's used for configuring CBS in AVB TX queues. that's the tea. 🍵 no cap, that's the entire description — iconic minimalism, honestly.

🔥 SEE ALSO 🔥

okay this is the part where the manpage shows off its whole friend group. every single one of these, bestie — no skipping, no "etc." 🙈

and that's the page!! 🌈 tiny manpage, huge energy, zero filler. this one came from ./drivers/net/ethernet/stmicro... and it's stamped October 2026 — so mark your calendars, bestie, and go configure those AVB TX queues. 💖⭐🍓
