dpsw_fdb_add_unicast(9)

💅 dpsw_fdb_add_unicast(9) — the Kernel API Manual, section 9, bestie ✨

Okay so picture this: you're deep in the kernel API manual (section 9, obviously), and you stumble onto dpsw_fdb_add_unicast. That's the function's whole name and title, and yes, we're gonna say it out loud every time because it slays.

---

🌸 NAME 🌸

dpsw_fdb_add_unicast — this function adds an unicast entry into the MAC lookup table. That's it. That's the vibe. 💖

---

✨ SYNOPSIS ✨

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

Like, look at that signature. Gorgeous. Returns an int, takes five things, we'll get to each one, don't panic 🫶

---

🎀 ARGUMENTS 🎀

Every single one, no skipping, periodt:

• mc_io — Pointer to MC portal's I/O object. Yeah, a pointer, it's giving main character energy.
• cmd_flags — Command flags; one or more of 'MC_CMD_FLAG_'. Note the trailing underscore bestie, that's intentional, don't come for me.
• token — Token of DPSW object. It's a u16 and it's your little object ID badge 💅
• fdb_id — Forwarding Database Identifier. Your FDB gets an id, and this is it.
• cfg — Unicast entry configuration. It's a const struct dpsw_fdb_unicast_cfg * and it holds the actual entry details, so fill it in before you call, mwah.

---

🔥 RETURN 🔥

Completion status. '0' on Success; Error code otherwise. That's the whole story — zero means slay, anything else means go read your error code 😭

Ngl this page is short and sweet — one function, one job, one MAC lookup table entry. But the see-also list is a whole friend group so don't say I didn't warn you 🫶

And that's the page, bestie! This little gem came from ./drivers/net/ethernet/freesca... (yeah, the footer truncates it exactly like that, iconic) and it's dated October 2026. Stan. 💖🎀✨
