In addition to supporting a variety of features 23 expected in a traditional hardware switch, it enables fine-grained 24 programmatic extension and flow-based control of the network. This 25 control is useful in a wide variety of applications but is 26 particularly important in multi-server virtualization deployments, 27 which are often characterized by highly dynamic endpoints and the 28 need to maintain logical abstractions for multiple tenants. 29 30 The Open vSwitch datapath provides an in-kernel fast path for packet 31 forwarding. It is complemented by a userspace daemon, ovs-vswitchd, 32 which is able to accept configuration from a variety of sources and 33 translate it into packet processing rules. 34 35 See http://openvswitch.org for more information and userspace 36 utilities. 37 38 To compile this code as a module, choose M here: the module will be 39 called openvswitch. 40 41 If unsure, say N. 42 43config OPENVSWITCH_GRE 44 tristate "Open vSwitch GRE tunneling support" 45 depends on OPENVSWITCH 46 depends on NET_IPGRE 47 default OPENVSWITCH 48 help 49 If you say Y here, then the Open vSwitch will be able create GRE 50 vport. 51 52 Say N to exclude this support and reduce the binary size. 53 54 If unsure, say Y. 55 56config OPENVSWITCH_VXLAN 57 tristate "Open vSwitch VXLAN tunneling support" 58 depends on OPENVSWITCH 59 depends on VXLAN 60 default OPENVSWITCH 61 help 62 If you say Y here, then the Open vSwitch will be able create vxlan vport. 63 64 Say N to exclude this support and reduce the binary size. 65 66 If unsure, say Y. 67 68config OPENVSWITCH_GENEVE 69 tristate "Open vSwitch Geneve tunneling support" 70 depends on OPENVSWITCH 71 depends on GENEVE 72 default OPENVSWITCH 73 help 74 If you say Y here, then the Open vSwitch will be able create geneve vport. 75 76 Say N to exclude this support and reduce the binary size. 77
