+++ This bug was initially created as a clone of Bug #1857410 +++

Description of problem:

We have customers that are trying to use PXE in a UEFI environment (i,e. grub) on vlan tagged networks. They are able to configure (via their UEFI interactive menu) the hardware to use vlan tags for PXE requests, but grub is not adding a vlan tag to the request for the grub.cfg.

After talking with several grub maintainers this feature only currently exists in grub2 for the ppc64le platform (with OpenFirmware). This is a request for this feature on x86_64 platform (and perhaps other platforms if it makes sense and is possible).

Patches to be added:
