💅 mlx5dr_send_postsend_ste(9) — Kernel API Manual 💅

okay so bestie, this is the page for mlx5dr_send_postsend_ste(9) from the Kernel API Manual, and it’s giving “tiny function, very specific job.” The way she writes bytes into the hw cm? Obsessed. Let’s go. 🫶✨

✨ NAME ✨

mlx5dr_send_postsend_ste — write size bytes into offset from the hw cm. That’s it, that’s the whole aesthetic. 💖

🌸 SYNOPSIS 🌸

int mlx5dr_send_postsend_ste (struct mlx5dr_domain *dmn , struct
       mlx5dr_ste *ste , u8 *data , u16 size , u16 offset );

🎀 ARGUMENTS 🎀

• dmn — Domain. The struct mlx5dr_domain * bestie, main character energy fr fr. 👑
• ste — The ste struct that contains the data (at least part of it). Lowkey carrying at least some of the data, iykyk. 🦋
• data — The real data to send size data. The actual real data, no cap. 🍓
• size — for writing. The u16 size of the write, periodt. ✨
• offset — The offset from the icm mapped data to start write to this, for write only part of the buffer. Ngl, it’s the “start here” spot for partial-buffer writes. 🌈

🔥 RETURN 🔥

0 on success. That’s the whole return section — literally one value, and she ate. 👑

cute sign-off time: this page is from the Kernel API Manual, with the source/version footer bit showing ./drivers/net/ethernet/mellano..., dated October 2026. Bye bestie, go write those size bytes into offset from the hw cm. 🎀💖✨
