commit d445cc16a5ca451bc06a195825153bab87f2e07e
Diffs: http://openvswitch.org/cgi-bin/gitweb.cgi?p=openvswitch;a=commitdiff;h=d445cc16a5ca451bc06a195825153bab87f2e07e

ofproto-dpif: Use megaflows.
		
The commit configures the masks generated from megaflows and pushes
them through the dpif layer.

With this commit and a wildcard supporting OVS kernel module,
ovs-vswitchd's flow setup rate is very close to that of the Linux
bridge.

dpif: Log flow masks for "put" and "dump_next".
		
When debugging the system, it's useful to not just see the key but
also the mask.

commit 9b1a48c210ffa95c6323d5db05958aba35802c49
Diffs: http://openvswitch.org/cgi-bin/gitweb.cgi?p=openvswitch;a=commitdiff;h=9b1a48c210ffa95c6323d5db05958aba35802c49

ofproto-dpif: Handle failed flow 'put's.
		
If a flow cannot be installed in the datapath, we should notice
this and not treat it as installed.  This becomes an issue with
megaflows, since a batch of unique flows may come in that generate
a single new datapath megaflow that covers them.  Since userspace
doesn't know whether the datapath supports megaflows, each unique
flow will get a separate flow entry (which overlap when masks are
applied) and all except the first will get rejected by a megaflow-
supporting datapath as duplicates.

odp-util: Introduce odp_flow_key_from_mask().
		
Add a new function for converting a mask into a set of
OVS_KEY_ATTR* attributes.  This will be useful in a future commit.
