2018-07-08openvswitch: kernel datapath clone actionYifeng Sun
Add 'clone' action to kernel datapath by using existing functions. When actions within clone don't modify the current flow, the flow key is not cloned before executing clone actions. This is a follow up patch for this incomplete work: https://patchwork.ozlabs.org/patch/722096/ v1 -> v2: Refactor as advised by reviewer.

2013-02-22openvswitch: Allow OVS_USERSPACE_ATTR_USERDATA to be variable length.Ben Pfaff
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.

2013-01-07linux/openvswitch.h: Make OVSP_LOCAL 32-bit.Jarno Rajahalme
OVS ports are now 32-bit, so OVSP_LOCAL should be too. (Internally, kernel module still keeps port numbers 16-bit, though.) Signed-off-by: Jarno Rajahalme <jarno.rajahalme@nsn.com> Signed-off-by: Jesse Gross <jesse@nicira.com>

2011-12-03net: Add Open vSwitch kernel components.Jesse Gross
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. Signed-off-by: Jesse Gross <jesse@nicira.com>
