idpf_tx_clean_bufs(9)

💅 idpf_tx_clean_bufs — a whole manual page, bestie

okay so this is idpf_tx_clean_bufs(9) straight out of the Kernel API Manual (yes, section 9, we love a numbered section) and it's basically the cleanup crew of the idpf TX world. let me tell you everything ✨

---

🌸 NAME 🌸

idpf_tx_clean_bufs — clean flow scheduling TX queue buffers. she cleans. that's the whole job. periodt. 🧹💖

---

🦋 SYNOPSIS 🦋

void idpf_tx_clean_bufs (struct idpf_tx_queue *txq , u32 buf_id , struct
libeth_sq_napi_stats *cleaned , int budget );

---

🎀 ARGUMENTS 🎀

• txq — the queue that's getting cleaned, aka struct idpf_tx_queue *, aka the main character here 👑
• buf_id — the packet's starting buffer ID, and ngl it comes straight from the completion descriptor 🫶
• cleaned — pointer to the stats struct that tracks the cleaned packets/bytes, because we stay documenting our wins 💅
• budget — used to determine if we are in netpoll. that's literally what it's for, no cap 😭

---

🔥 DESCRIPTION 🔥

so what she actually does: clean all the buffers associated with the packet starting at buf_id. yes, all of them. every single one. and then — the little flex at the end — she returns the byte/segment count for the cleaned packet 🌈✨

it's giving "I did the work AND I brought receipts." iconic behaviour, honestly.

⭐ SEE ALSO ⭐

okay this next part is a whole friend group, buckle up bestie, because the cross-reference list is LONG and we are not skipping a single one — every name below is exactly as written, promise 🙈💜
