the flow table across loading and unloading the OVS kernel module

flow table was still meaningful, it ensured that the datapath port
numbers were the same with the old and new versions of the kernel
module.

However, later commit e1b1d06afde (Separate OpenFlow port numbers
from datapath ones.) changed the OpenFlow implementation so that
keeping the same datapath port numbers no longer ensured that the
OpenFlow port numbers would be the same.  This caused a regression
in saving and restoring the flow table.  Although the flow table
was still saved and restored, it was no longer useful, since the
datapath port numbers might change.

Ben Pfaff [Fri, 2 Nov 2012 17:37:59 +0000 (10:37 -0700)]
ofproto: Better hide hidden tables.

ofproto has a concept of "hidden" OpenFlow tables.  Currently these are
used internally only for ofproto-dpif for a couple of unimportant
purposes.  However, hidden tables were not hidden well enough, because
OFTest was able to spot ofproto-dpif's hidden table and, seeing that it
had a couple of flows in it even after OFTest had tried to delete all
flows, failed at least one test.

This commit hides the tables better:

    - The number of tables reported in a feature reply no longer counts
      hidden tables.

    - Table stats replies omit hidden tables.

This commit introduces the requirement that hidden tables, if any, be the
highest-numbered tables.  This is because it's not clear to me that
OpenFlow intends to allow tables to be numbered noncontiguously.

We could take this further, by not exposing hidden tables in any way, but
I have this pet theory that being able to get the statistics for these
tables will come in handy for debugging someday.

ofproto-dpif: Use a single underlying datapath across multiple bridges.

This commit switches to using a single backing datapath (called
"ovs-datapath") for all bridges of that datapath's type.  Previously,
resources couldn't be shared across bridges, since each was in its own
datapath.  This change will allow sharing of tunnels and cheaper patch
ports to be added in the future.

Since bridges share a common datapath, the ovs-dpctl commands won't
provide bridge-specific information.  Users wishing to have that
information should use the new "ovs-appctl dpif/*" commands as
documented in ovs-vswitchd(8).
