dpsw_vlan_remove_if(9)

💅 dpsw_vlan_remove_if(9) — the dpsw_vlan_remove_if page, bestie edition 🎀

Okay so this is a page from the Kernel API Manual, and today's main character is dpsw_vlan_remove_if — literally the function that takes interfaces out of a VLAN that already exists. No cap, that's the whole job. 🦋

---

✨ NAME ✨

dpsw_vlan_remove_if — remove interfaces from an existing VLAN. That's it, that's the vibe. 💖

---

🌸 SYNOPSIS 🌸

int dpsw_vlan_remove_if (struct fsl_mc_io *mc_io , u32 cmd_flags , u16
token , u16 vlan_id , const struct dpsw_vlan_if_cfg *cfg );

Like, look at her. Five arguments, one int return, absolutely iconic. 👑

---

🎀 ARGUMENTS 🎀

• mc_io — pointer to the MC portal's I/O object. Your whole entry point to the magic, fr.
• cmd_flags — command flags; one or more of 'MC_CMD_FLAG_'. Pick your flags, babe.
• token — the token of the DPSW object. It's giving VIP wristband at the club. 🫶
• vlan_id — the VLAN Identifier. Which VLAN we're bothering today.
• cfg — the set of interfaces that should be removed. Like a hit list but for interfaces, lowkey. 💀

---

🦋 DESCRIPTION 🦋

So here's the tea: the interfaces must belong to this VLAN. That's non-negotiable, bestie. If they don't? An error is returned and the command is just... ignored. Straight up ghosted. 😭

Not me about to remove an interface from a VLAN it was never in 🙈 — don't do that. You'll get an error and the command won't even run. Vibe check failed.

---

⭐ RETURN ⭐

Completion status. '0' on success, error code otherwise. Zero is the slay, anything else is a cry. 💜
