fcoe_rcv(9)

💖 fcoe_rcv(9) 💖

okay so bestie, welcome to the fcoe_rcv page from the Kernel API Manual — this is the whole vibe: receiving packets from a net device. no cap, it's a little function with a big job. 🦋

---

✨ SYNOPSIS ✨

int fcoe_rcv (struct sk_buff *skb , struct net_device *netdev , struct
packet_type *ptype , struct net_device *olddev );

like… four arguments, one int return, extremely demure, extremely mindful. 💅

---

🎀 ARGUMENTS 🎀

• skb — the received packet itself, the main character of this whole situation 👑
• netdev — the net device that the packet was received on, aka where it showed up
• ptype — the packet type context, keeping track of the packet-type lore
• olddev — the last device net device 🫶

---

🌸 DESCRIPTION 🌸

so here's the tea: this routine is called by NET_RX_SOFTIRQ. it receives a packet, builds an FC frame, and passes that frame to libfc. that's the whole arc, and honestly? iconic. ✨

---

⭐ RETURN ⭐

0 for success — that's it, that's the return. slay. 💜
