dpsw_fdb_add(9)

✨ dpsw_fdb_add(9) ✨

okay bestie, so this one lives in the Kernel API Manual and it's literally the dpsw_fdb_add situation — a kernel-level function that adds an FDB to a switch and hands you back a handle to the FDB table for reference 💅 no cap, that's the whole vibe.

---

🦋 SYNOPSIS 🦋

int dpsw_fdb_add (struct fsl_mc_io *mc_io , u32 cmd_flags , u16 token ,
u16 *fdb_id , const struct dpsw_fdb_cfg *cfg );

it's giving "one function, five arguments, zero chill" ✨

---

🌸 ARGUMENTS 🌸

• mc_io — Pointer to the MC portal's I/O object. like, the door you knock on 🚪
• cmd_flags — Command flags; one or more of 'MC_CMD_FLAG_'. pick your flags, bestie 🎀
• token — Token of DPSW object. iykyk 🔑
• fdb_id — Returned Forwarding Database Identifier. yes, it comes back to you, main character energy 👑
• cfg — FDB Configuration. the settings, the setup, the whole look ⭐

---

💖 RETURN 💖

Completion status. '0' on Success; Error code otherwise. so like, 0 = slay, anything else = go read the error code 😭

bestie reminder: fdb_id is a pointer — the identifier gets written back through it, so don't go handing it garbage, mwah 🫶
