There is a change in behavior - the service is not enabled

ofproto-dpif: Make ofproto/trace a bit more like real packet translation.

can do the flow lookup internally and, since that is what happens when a
packet arrives, having it do its own packet lookup makes a lot of sense.

I noticed this in connection with the actset_output field, which
xlate_actions() should set to OFPP_UNSET at the beginning of translation
before looking up the flow.  ofproto/trace didn't do that, so it looked
up a rule with actset_output=0 instead.  By having xlate_actions() do the

- only support small set of important keywords

- does not support parsing of nested options

- does not support expansion on repeatitive argument

- only support matching on long options, and only in the format

2. Install and Uninstall the OVS EXT Driver (with enabling the OVS

9 years agodatapath-windows: Update vport add code.
Nithin Raju [Fri, 24 Oct 2014 00:33:13 +0000 (17:33 -0700)]
datapath-windows: Update vport add code.

In this patch, we make the following updates to the vport add code:

1. Clarify the roles of the different hash tables, so it is easier to
   read/write code in the future.
2. Update OvsNewVportCmdHandler() to support adding bridge-internal
   ports.
3. Fixes in OvsNewVportCmdHandler() to support adding external port.
   Earlier, we'd hit ASSERTs.
4. I could not figure out way to add a port of type
   OVS_PORT_TYPE_INTERNAL with name "internal" to the confdb using
   ovs-vsctl.exe. And, this is needed in order to add the Hyper-V
   internal port from userspace. To workaround this problem, we treat a
   port of type OVS_PORT_TYPE_NETDEV with name "internal" as a request
   to add the Hyper-V internal port. This is a workaround. The end
   result is that there's a discrepancy between the port type in the
   datpaath v/s confdb, but this has not created any trouble in testing
   so far. If this ends up becoming an issue, we can mark the Hyper-V
   internal port to be of type OVS_PORT_TYPE_NETDEV. No harm.
5. Because of changes indicated in #1, we also update the vport dump
   code to look at the correct hash table for ports added from
   userspace.
6. Add a OvsGetTunnelVport() for convenience.
7. Update ASSERTs() while cleaning up the switch.
8. Nuke OvsGetExternalVport() and OvsGetExternalMtu().

2. s/OvsInitVportCommon/InitHvVportCommon - this function is common code

3. Introduce a InitOvsVportCommon() that is common code for evrey port
   that gets added from userspace. This is especially useful for ports
   that are not present on the Hyper-V switch. ie. tunnel ports and
   bridge-internal ports.
4. Fix OvsClearAllSwitchVports() to remove ports from both the lists:
   the ones added from Hyper-V as well as the ones added from OVS
   userspace.
5. Update OvsInitVxlanTunnel() to not call into InitHvVportCommon
   (formerly OvsInitVportCommon()) since it is not a port on the Hyper-v
   switch. In a later patch in the series, we'll call
   InitOvsVportCommon() for a VXLAN port.
6. 'numNonHvVports' increments and decrements ONLY for ports that are
