[Bug 1125611] [NEW] Upgrade to 1.4.0-1ubuntu1.4 breaks brcompat support

[Sebastian Marsching]

Public bug reported:

On Ubuntu 12.04.2 LTS, after an automatic upgrade from openvswitch
1.4.0-1ubuntu1.3 to openvswith 1.4.0-1ubuntu1.4 the brcompat support
does not work any longer.

The brcompat kernel module can be build, installed, and loaded, but
openvswitch-brcompatd will not start with the error message: "ovs-
brcompatd: could not open brcompat socket. Check "brcompat" kernel
module."

After a downgrade back to version 1.4.0-1ubuntu1.3 brcompat works again.
I think this is essentially the same problem as described here:
https://answers.launchpad.net/ubuntu/+source/openvswitch/+question/221334

It might be unrelated, but after the upgrade "lsmod" does not list the
"openvswitch" module as a dependency of the "brcompat" module. After
downgrading, the dependency is shown again.
