Maybe I am missing something in the setup, but I am not getting
host-to-host connectivity. I booted a switch with this patch, configured
a bridge:
# ip a sh dev br0
44: br0: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc noqueue state
UP group default qlen 1000
link/ether 7c:fe:90:e8:3a:79 brd ff:ff:ff:ff:ff:ff

valid_lft forever preferred_lft forever
inet6 fe80::7efe:90ff:fee8:3a79/64 scope link

The switch can see the hosts:
