You need to build iPXE with VLAN support enabled.  The easiest way to do 
this is to enable the VLAN commands (VLAN_CMD) in config/general.h.

This will give you the commands "vcreate" and "vdestroy", which are 
documented with examples at

   http://ipxe.org/cmd/vcreate
   http://ipxe.org/cmd/vdestroy

You can use vcreate to create a VLAN interface from the trunk network 
interface, and you can then do whatever you want over this VLAN 
interface.  For example:

   #!ipxe
   vcreate --tag 45 net0
   autoboot net0-45
