This should work. I used to have a similar setup, but I no longer
have it handy. The following is based on my notes:
The VM where lwip ran did
brctl addbr bridge0
brctl addif bridge0 eth1
ifconfig bridge0 up
once to init things.
Then tapif.c had changed
#define IFCONFIG_ARGS "tap0 up # %d.%d.%d.%d"
and additional
status = system("brctl addif bridge0 tap0");
at the end of low_level_init() since tap0 is removed from the bridge
when closed and needs to be added back when tapif.c opens it anew.
Note that neither bridge, nor tap has ip addresses configured.
