✨ NAME ✨

dpsw_fdb_remove — Remove FDB from switch 💅

no cap, that's the whole vibe: FDB? gone. switch? cleaner. periodt.

🌸 SYNOPSIS 🌸

int dpsw_fdb_remove (struct fsl_mc_io *mc_io , u32 cmd_flags , u16 token
, u16 fdb_id );

like look at her 🫶 four args, returns an int, she's not complicated, she just gets the job done.

---

🦋 ARGUMENTS 🦋

• mc_io — Pointer to MC portal's I/O object 🌈 this is your lil doorway into the MC portal, don't lose her.
• cmd_flags — Command flags; one or more of 'MC_CMD_FLAG_' ⭐ flags flags flags, pick your faves from the 'MC_CMD_FLAG_' set.
• token — Token of DPSW object 🔑 that's the DPSW's token, her little ID bracelet basically.
• fdb_id — Forwarding Database Identifier 👑 the actual FDB you're saying bye to.

lowkey the most important part: know which fdb_id you're removing before you remove it 🙈
