Until now, the optional OVS_USERSPACE_ATTR_USERDATA attribute had to be
exactly 64 bits long, if it was present. However, 64 bits is not enough
space to associate as much information with a flow as would be convenient
for some userspace features now under development. This commit generalizes
the attribute, allowing it to be any length.
This generalization is backward-compatible: if userspace only uses 64-bit
attributes, then it will not see any change in behavior.

OVS ports are now 32-bit, so OVSP_LOCAL should be too.
(Internally, kernel module still keeps port numbers 16-bit, though.)

Open vSwitch is a multilayer Ethernet switch targeted at virtualized
environments. In addition to supporting a variety of features
expected in a traditional hardware switch, it enables fine-grained
programmatic extension and flow-based control of the network.
This control is useful in a wide variety of applications but is
particularly important in multi-server virtualization deployments,
which are often characterized by highly dynamic endpoints and the need
to maintain logical abstractions for multiple tenants.
The Open vSwitch datapath provides an in-kernel fast path for packet
forwarding. It is complemented by a userspace daemon, ovs-vswitchd,
which is able to accept configuration from a variety of sources and
translate it into packet processing rules.
See http://openvswitch.org for more information and userspace
utilities.
