Andres, good catch, thanks for the reminder; I had skipped over that
part of the original bug report.
The additional attached patch lower cases the MAC address too; maybe the code
would be rewritten to have two vars and a loop instead of calling sprintf, I'll
check with Jason what he prefers. With this additional patch, I get the
expected lowercasing:

Another thing I noticed from my earlier comment comparing pxelinux and u-boot:
pxelinux doesn't send a DHCP request itself, so it doesn't make sense to
compare the place where they get the UUID from; pxelinux does the meaningful
thing in trying to read the uuid from the reply packet cached by the network
card's PXE ROM (it might have been set in the request or in the reply), and
u-boot-linaro does the meaningful thing in setting it in the request.
