Why is that? During the scan, SeaBIOS finds two devices with id 10ec:8167, and thus copies the rom from CBFS twice. I suppose gpxe could be smart enough to resize itself to zero, but it is not doing that today. (Though, gpxe tries to use PMM - it might be smarter when that is available.)

That's a good reason. Thanks.

True - but gpxe seems smart enough to boot any device it supports after being called just once. I guess I'll ask the gpxe maintainers if they can optimize this on their end.
