fcoe_ddp_setup(9)

💅 NAME 💅

Okay so bestie, welcome to the Kernel API Manual moment for fcoe_ddp_setup(9) — the function whose whole serve is to call a LLD's ddp_setup through the net device. That's the assignment. No cap. ✨

✨ SYNOPSIS ✨

Here's the exact signature, character for character, because we do not play with code:

int fcoe_ddp_setup (struct fc_lport *lport , u16 xid , struct
scatterlist *sgl , unsigned int sgc );

🎀 ARGUMENTS 🎀

• lport — the local port to setup DDP for, periodt. 💖
• xid — the exchange ID for this DDP transfer. Keep it cute, keep it exact.
• sgl — the scatterlist describing this transfer. It's giving "here's the data map" energy.
• sgc — the number of sg items. Yes, a count. We love a count. 🎀

🌸 RETURN 🌸

The documented return is 0 if the DDP context was not configured. That's the whole return tea, bestie — no extra lore added. 💀
