Hi Don,
Attach the diff/patch and post it to the mailing-list. You can also send
a pull request to the iPXE Github repo. If you use the github repo then
it should also be easy for others to apply it until someone can merge it
to mainline (better visibility).

I noticed that the correct MAC address is reported as "autoloaded" but the preferred address (ie the one used is the one read from the eeprom/invm) and I was wondering why? I changed to logic to be if the autoloaded MAC address is valid then use it, otherwise try to read the eeprom or invm based on the device. Is there a reason the autoloaded address is not used by default?

The board has 4 ethernets, one (eth0) is a i217-LM and reports the proper MAC address. The other three are the troublesome i210-LT Flashless Copper devices. I am guessing that the iPXE intel driver has not been updated to support the flashless device. From other patches I have seen (linux) it looks like the MAC address needs to be read differently for the "flash-less" devices.

>> Also MAC address being reported for the three devices is bogus. If I boot linux, I can view the mac addresses and they are what I expect (correct first 3 hex digits for vendor, etc..). ifconf reports the same MAC address for all three and it does not have the right vendor OUI.. The driver is working somewhat in that the link state is reported correctly. If I unplug the link and ifconf the link is reported as down. Plugged in and it is reported as up.
