Hi,
If SIOCSIFNAME is used to change the name of the tap interface it seems to
work on FreeBSD 10.1:
ovs-netdev: flags=ffdc8802<BROADCAST,SIMPLEX,MULTICAST,MONITOR,STATICARP>
metric 0 mtu 1500
options=80000<LINKSTATE>
ether 00:bd:43:48:02:00
nd6 options=21<PERFORMNUD,AUTO_LINKLOCAL>
media: Ethernet autoselect
status: no carrier
br0: flags=ffdc8802<BROADCAST,SIMPLEX,MULTICAST,MONITOR,STATICARP> metric 0
mtu 1500
options=80000<LINKSTATE>
ether 00:30:18:c0:44:c4
nd6 options=21<PERFORMNUD,AUTO_LINKLOCAL>
media: Ethernet autoselect
status: no carrier
After you mentioned that the problem may be with the tap interface I
remembered that at some point I had created a tap0, in am attempt to get
OVS working. I think the existence of this tap interface may have been
causing the problems that I have been seeing. I still see some warnings and
errors but it looks like the bridge may be working.
Atanu.
