/*
 * Proxmox VE - VLAN Trunks UI Plugin
 * Adds a "Trunks" field to the QEMU VM Network Device editor.
 *
 * The PVE network parser/printer (PVE.Parser) already understands the
 * `trunks=` option; only the UI field is missing. This override adds it.
 *
 * Install: place in /usr/share/pve-manager/js/ and load it after
 * pvemanagerlib.js via the index template (see install.sh).
