velocity_rx_copy(9)

✨ velocity_rx_copy ✨

Okay so this is the manual page for velocity_rx_copy, bestie — it's giving kernel API realness from the velocity_rx_copy(9) corner of the manual-verse, and we're about to get into it. 💅

🌸 NAME 🌸

velocity_rx_copy — in place Rx copy for small packets

Like, it copies stuff for received packets but in place and only when they're smol. Iconic behavior honestly.

---

🦋 SYNOPSIS 🦋

int velocity_rx_copy (struct sk_buff **rx_skb , int pkt_size , struct
velocity_info *vptr );

That's the whole vibe right there. Three args, returns an int. Slay.

---

🎀 ARGUMENTS 🎀

• rx_skb — the network layer packet buffer candidate. It's the skb that's like, in the running to be the one, y'know? The candidate. 👑
• pkt_size — the received data size. Literally how much data we received, no cap.
• vptr — the velocity adapter. That's our main character struct fr fr.

---

💖 DESCRIPTION 💖

Here's the tea: this function replaces the current skb that is scheduled for Rx processing with a shorter, immediately allocated skb — but only if the received packet is small enough. So it's like a glow-up swap for tiny packets. ✨

And listen, if the received packet is too big? Or if memory is exhausted? This function returns a negative value. So yeah, negative return = something went wrong, bestie. Not the vibe. 😭💀

And that's the page, bestie! This lil beauty lives in ./drivers/net/ethernet/via, dated October 2026, and honestly? She's serving kernel API realness and we're obsessed. 💜🎀🦋
