Public bug reported:
I set up a bridge (linux bridge, also tried ovs bridge), with two taps.
Two qemu vms, one using each tap, using virtio or e1000. Ran one as
dnsmasq+pxe server, the other '-boot n'. Watching traffic on the bridge
and each tap device, i could verify that boots replied to bootc
requests, and the booting vm's tap did receive that reply. But it would
just keep re-issuing its bootc request.
When I build ipxe from git and install the result, it works.
This was happening with 19.04. I'm going to upgrade, I assume it's
fixed in 20.04 and probably 19.10, but will reply here. But the bug
should be open to save other people the hours I wasted trying to find a
bug in the bridge code, until 19.04 is EOL.
