The latter. There were patches to add tagged VLAN support (and they are

UEFI patches.
I am not sure how we should proceed with auto-configuration either. It
does not look like PXE_BASE_CODE_MODE structure contains information
about VLAN. So we probably need to somehow query interface. Someone
having such configuration is welcomed to provide patches :)
ofnet is easier because we get this information directly from firmware.
On UEFI someone needs to find out how to get this information.
Yeah, looking at
http://dox.ipxe.org/structEFI__PXE__BASE__CODE__MODE.html it does not
seems to contain any VLAN info for EFI boot as well.
I am just wondering if the VLAN defined prior to booting (i.e. via the
UEFI-BIOS) is transparent to the software doing the network boot and the
NIC simply tags all frames. iPXE does have VLAN support though, so
somehow configuration of VLANs is possible, see
http://ipxe.org/buildcfg/vlan_cmd .

Christian
