Unrecognised TCP/IP protocol There is a lot of stuff going on in networks that iPXE don't care about, but it is still logged.

if you see this output from ifstat ignore it unless you are trying to support a new protocol or is having really weird network corruption, but you might want to check with tcpdump/wireshark first if there is an explanation.
