If I'm reading that picture correct you are using commit
https://git.ipxe.org/ipxe.git/26050fd which is from 8 Dec 2016
Please try with latest git master and see if that makes any difference

Which binary of iPXE are you using?
undionly,kpxe reuses the existing PXE stack and is the closest to what
most other NBPs do
ipxe.pxe on the other hand has it's own native drivers for each NIC,
which unloads the existing PXE stack and installs it's own. (this
gives better performance in most cases and also enables additional
features)

Start with testing with latest version of iPXE, also test if you have
different behavior between undionly.kpxe and ipxe.pxe
