Comment 1 for bug 1618987

It's actually trying to set the MAC address, either way the port isn't there.

So I'm pretty good at finding red herrings. Since there was a port added right before this one I found the name in ovs-vswitchd.log. There were only two occurrences:

2016-08-30T23:14:21.077Z|00731|bridge|INFO|bridge test-brf4f80ab5: added interface portcfbbde on port 3
2016-08-30T23:14:21.243Z|00735|netdev_linux|INFO|ioctl(SIOCGIFHWADDR) on portcfbbde device failed: No such device

porta0d188 had two hits as well, but both were adding it:

2016-08-30T23:14:21.231Z|00732|bridge|INFO|bridge test-br103b76e6: added interface porta0d188 on port 5
2016-08-30T23:14:21.350Z|00740|bridge|INFO|bridge test-br103b76e6: added interface porta0d188 on port 5

The log is pretty big, but I couldn't find another occurrence where a port was added twice in a row, seemed odd.

The functional test log seems to show a clean DelPortCommand/AddPortCommand/DbSetCommand for the port though.
