xemaclite_send(9)

📦 version 7.3.1, in nixpkgs unstable

💅 xemaclite_send — from the Kernel API Manual ✨

okay so bestie, buckle up, because we're talking about xemaclite_send(9) today and honestly? she's iconic. 🎀

🌸 NAME 🌸

xemaclite_send — literally just transmit a frame. that's it. that's the whole vibe. 💌

✨ SYNOPSIS ✨

netdev_tx_t xemaclite_send (struct sk_buff *orig_skb , struct net_device
*dev );

no cap, that's the signature. memorize it, screenshot it, put it on your wall. 🫶

🦋 ARGUMENTS 🦋

  • orig_skb — pointer to the socket buffer that's about to get transmitted. she's the package. the moment. the main character. 📦
  • dev — pointer to the network device. the venue where all of this goes down. 🎪

🔥 DESCRIPTION 🔥

so here's the tea ☕ — this function first does a vibe check on the Emaclite device's Tx buffer to see if it's free to send data. if it is? slay. it fills that Tx buffer up with the data from the socket buffer, updates the stats, and frees the socket buffer. periodt. 💅

the Tx completion gets signaled by an interrupt — that's how you know it's done, iykyk.

but if the Tx buffer is not free? not me having to defer 😭 — in that case the socket buffer gets deferred and the Tx queue is stopped, so that the deferred socket buffer can be transmitted later, whenever the Emaclite device is free to transmit data again. lowkey a whole queue-and-wait situation. the way that works is honestly kind of genius. 🌈

👑 RETURN 👑

NETDEV_TX_OK, always. fr fr. no other answer. that's her only answer. ⭐
