Subject: [GIT net-next] Open vSwitch

Following patches introduces flow mask cache. To process any packet
OVS need to apply flow mask to the flow and lookup the flow in flow table.
so packet processing performance is directly dependant on number of entries
in mask list.

Following patch adds mask cache so that we do not need to iterate over
all entries in mask list on every packet. We have seen good performance
improvement with this patch.

Before the mask-cache, a single stream which matched the first mask
got a throughput of about 900K pps. A stream which matched the 20th mask
got a throughput of about 400K pps. After the mask-cache patch, all
streams throughput went back up to 900K pps.
