💅 dpsw_fdb_remove_unicast(9) — bestie's guide to yeeting a MAC entry

okay so picture this: you're deep in the Kernel API Manual (that's the manual name, keep it in your notes 📓) and you need dpsw_fdb_remove_unicast to removes an entry from MAC lookup table. That's it. That's the whole personality. It's giving cleanup era ✨ and honestly we love a function that knows its job and does it.

🌸 NAME 🌸

dpsw_fdb_remove_unicast — removes an entry from MAC lookup table

like literally, one entry, out of the MAC lookup table, gone. byeee 👋

---

🎀 SYNOPSIS 🎀

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

five args, one int coming back at you. no cap, that's the whole signature, copy it exactly bestie 🫶

---

✨ ARGUMENTS ✨

• mc_io — Pointer to MC portal's I/O object. this is your main character handle, the portal vibe itself 💫
• cmd_flags — Command flags; one or more of 'MC_CMD_FLAG_'. pick your flags like you're picking an outfit, there's a whole prefix family for it 👑
• token — Token of DPSW object. yes the DPSW object has a token, treat it with respect 🎟️
• fdb_id — Forwarding Database Identifier. which FDB are we ghosting? this number. 🔢
• cfg — Unicast entry configuration. a const struct dpsw_fdb_unicast_cfg *, so nobody's touching it, it's just here to tell us what the entry looks like 🦋

---

🔥 RETURN 🔥

Completion status. '0' on Success; Error code otherwise.

so bestie, if you get 0 back — slay, the entry is gone, pop the confetti 🎉. anything else? that's an error code and the vibe check failed, go read it 😭
