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 that will not be offloadable.

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.
