It looks as though the NII interface is reporting that it _does_ support 
link status (since PXE_STATFLAGS_GET_STATUS_NO_MEDIA_SUPPORTED is not 
set), but is then never reporting the link as being up.

As a first suggestion, try upgrading from UEFI boot to BIOS boot.

If that doesn't work, then you could try editing nii_get_init_info() to 
force nii->media=0 (which would cause iPXE to assume that the NII 
interface does not support link status, and consequently to assume that 
the link is unconditionally up).
