By arbitrary IP address I mean defining ip_src=10.0.1.3 to 10.0.1.128
just as one rule. Current classifier in openvswitch uses hashcode of the
wildcard bit pattern to create a hashset for rules having the same
wildcard bit pattern. OVS new flow setup time benefits from this
limitation. Supporting this kind of rules needs a big change in the
architecture.

Is there any plan to support wildcards on TCP port fields (eg:1024
to 2048) and arbitrary wildcards on IP addresses?
Is anyone aware of an implementation that can support these kind of rules?
Open vSwitch supports bitwise matching on TCP port fields. It doesn't
currently support arbitrary wildcards on IP addresses but it would be
easy to add.
