batadv_tp_handle_ack(9)

💅 batadv_tp_handle_ack(9) — the kernel API manual, but make it make sense

okay bestie, so this is a page from the Kernel API Manual and it's called batadv_tp_handle_ack — no cap, that's the whole name up top, we're just folding it in here so it doesn't look all formal and weird 💖

---

✨ NAME ✨

batadv_tp_handle_ack — the function that calculates the reaction to an ACK and updates congestion control. that's it, that's the vibe 🦋

---

🌸 SYNOPSIS 🌸

enum batadv_tp_ack_reaction batadv_tp_handle_ack (struct batadv_priv
*bat_priv , struct batadv_tp_sender *tp_vars , u32 recv_ack , size_t mss
);

lowkey iconic signature, honestly. it hands you back an enum batadv_tp_ack_reaction and takes four things 👑

---

🎀 ARGUMENTS 🎀

• bat_priv — the bat priv with all the mesh interface information. it's giving "everything you ever wanted to know about the mesh", fr fr.
• tp_vars — the private data of the current TP meter session. this session's personal little diary 🍓
• recv_ack — received ACK seqno. the sequence number of the ACK we just got, bestie.
• mss — maximum segment size for transmission. big "how chunky can my segments be" energy.

---

⭐ RETURN ⭐

returns the expected reaction to this ack. that's the whole deal — the answer is a reaction, and it's an enum batadv_tp_ack_reaction. slay 💅

okay this list is long and it ate, so buckle up bestie, we're going through all of it 🙈

🧚 cute lil sign-off 🧚

this page lives in ./net/batman-adv, and it's dated October 2026 — yes, the future, she's ahead of her time ✨ and the header/footer name for the whole thing is batadv_tp_handle_ack(9), so now you know where to find her again. bye bestie, go update that congestion control 🌈🫶💜
