Add a test to verify sampling packets via psample works.
In order to do that, create a subcommand in ovs-dpctl.py to listen to
on the psample multicast group and print samples.

The trunc action was supported decode-able but not parse-able. Add

The userspace action lacks parsing support plus it contains a bug in the
name of one of its attributes.
This patch makes userspace action work.

When a packet sample is observed, the sampling rate that was used is
important to estimate the real frequency of such event.
Store the probability of the parent sample action in the skb's cb area
and use it in psample action to pass it down to psample module.

Add support for a new action: psample.
This action accepts a u32 group id and a variable-length cookie and uses
the psample multicast group to make the packet available for
observability.
The maximum length of the user-defined cookie is set to 16, same as
tc_cookie, to discourage using cookies th
Although not explicitly documented in the psample module itself, the
definition of PSAMPLE_ATTR_SAMPLE_RATE seems inherited from act_sample.
Quoting tc-sample(8):
"RATE of 100 will lead to an average of one sampled packet out of every
100 observed."
With this semantics, the rates that we can expr
If nobody is listening on the multicast group, generating the sample,
which involves copying packet data, seems completely unnecessary.

Add a user cookie to the sample metadata so that sample emitters can

If present, send the user cookie in a new attribute:

** Background **
Currently, OVS supports several packet sampling mechanisms (sFlow,
per-bridge IPFIX, per-flow IPFIX). These end up being translated into a
