[ovs-dev] [lacp 01/10] vswitchd: Iface destruction should result in flow revalidation.

[Ben Pfaff]

I think that revalidation here is redundant with calling
bridge_flush().  If you trace through that function's effects, you can
see that it eventually causes every facet to be revalidated.

I don't know why we do other explicit revalidation here.  I guess that
I didn't realize that it wasn't necessary.

If we can actually get rid of the flush, that would be awesome, but
that would take a more careful audit.
