To date, this error has only occurred within the end user environment, I have been unable to recreate it in my lab.  I'm looking for options to increase the value of our debugging with the end user.  The network card being used is a Dell branded Intel X710 4 port SFP daughter card pci identifier 8086:1572:1028:0000.

The message

ASSERT
u:\MdePkg\Library\UefiMemoryAllocationLib\MemoryAllocationLib.c(819):
!EFI_ERROR (Status)

is coming from the EDK2 FreePool() function:

 
https://github.com/tianocore/edk2/blob/master/MdePkg/Library/UefiMemoryAllocationLib/MemoryAllocationLib.c#L819

There are only a few places in iPXE that use FreePool().  You can enable 
debug for all of them using:

 
DEBUG=nii,efi_block,efi_driver,efi_fbcon,efi_local,efi_pci,efi_snp_hii,efi_usb

Are you able to provide remote console access to an environment in which 
the problem can be reproduced?

Thanks,

Michael
