It is version 6.03.  I will attempt to use the latest from the repo and 
report back.

The system is a Dell PowerEdge R730xd with 4 NICs:
Intel(R) Ethernet 10G 4P X520/I350 rNDC
Intel(R) Gigabit 4P X520/I350 rNDC

Current connection on the 10G port.

I have noticed something else a little weird via the UEFI setting for 
the NIC's.  I seem to have to enable two NICs for PXE booting to even 
successfully PXE boot.  When I do this the first NIC fails to boot and 
the second works right away.  Doesn't matter which interface boots first 
or which is plugged in.  I will probably open a ticket about this with 
Dell, just thought it was a little weird.
