So there are two "issues" here:

1. The lack of transporting the information about a VLAN tag being used 
to bootstrap (UEFI-PXI boot to Grub2) into grub itself. As I understand 
such variables are usually available with the "net_pxe_" prefix?

2. User interface to even manually do anything regarding vlans. This 
would at least enable some sort of "hard coding" a VLAN and continue to 
boot even without the dynamic info about the used VLAN from issue 1.


As this scenario is not uncommon, think hypervisor host with just one 
interface which is a VLAN trunk, how should I go about filing issues for 
this?
