Ido Schimmel	a9b5d871ab	netdevsim: Only use sampling truncation length when valid ... When the sampling truncation length is invalid (zero), pass the length of the packet. Without the fix, no payload is reported to user space when the truncation length is zero.

Ido Schimmel	a8700c3dd0	netdevsim: Add dummy psample implementation ... Allow netdevsim to report "sampled" packets to the psample module by periodically generating packets from a work queue. The behavior can be enabled / disabled (default) and the various meta data attributes can be controlled via debugfs knobs. This implementation enables both testing of the psample module with all the optional attributes as well as development of user space applications on top of psample such as hsflowd and a Wireshark dissector for psample generic netlink packets.
