    Migrate data from cap_port_filter to vif_details

    There was introduced a new column vif_details for ml2_port_binding table
    and dropped cap_port_filter column. Data was lost during the migration
    causing no data in vif_details.

    This patch transforms data from cap_port_filter to vif_details column as
    a part of db migration. MigrationContext.execute() calls underlaying
    methods depending whether migration is online or offline therefore data
    are migrated in offline migration too.

Hi Jakub,

Is there a need for neutron-side patch for this job? It seems to me it's been green for about 48 hours now, so perhaps we don't need any more patch (and therefore remove neutron from affected projects).

[Jakub Libosvar (libosvar)]

Hi Salvatore,

you are right. The Neutron side was fixed as a part of other reported bugs. Originally this bug was opened on Neutron simply because I was very new to launchpad at the time of opening this.

I'm getting error: "Timeout error, please try again in a few minutes" when trying to remove Neutron from affected projects. I'll try it later.

Thanks for pointing this out.
