beiscsi_iface_config_vlan(9)

💅 beiscsi_iface_config_vlan — a Kernel API Manual moment (section 9, bestie)

okay so we're in the Kernel API Manual, section 9, and today's main character is beiscsi_iface_config_vlan. she's short, she's sweet, she sets a VLAN tag. let's get into it 🎀

---

✨ NAME ✨

beiscsi_iface_config_vlan — literally just Set the VLAN TAG. that's the whole job. icon behavior.

---

🦋 SYNOPSIS 🦋

int beiscsi_iface_config_vlan (struct Scsi_Host *shost , struct
       iscsi_iface_param_info *iface_param );

she takes two args and hands you back an int. no cap.

---

🌸 ARGUMENTS 🌸

• shost — the Scsi Host for the driver instance. like, the actual host she's working with 💖
• iface_param — the Interface paramters. (yes that's how the page spells it, we don't gatekeep typos 💀) this is where the interface details live.

---

⭐ DESCRIPTION ⭐

so what does she do? she sets the VLAN TAG for the adapter, or — plot twist — she disables the VLAN config. two moods, one function, we love a flexible queen 👑

and the return situation:

returns Success: 0 Failure: Non-Zero Value

so 0 = slay, anything non-zero = something went sideways 😭
