In addition to supporting a variety of features 22 expected in a traditional hardware switch, it enables fine-grained 23 programmatic extension and flow-based control of the network. This 24 control is useful in a wide variety of applications but is 25 particularly important in multi-server virtualization deployments, 26 which are often characterized by highly dynamic endpoints and the 27 need to maintain logical abstractions for multiple tenants. 28 29 The Open vSwitch datapath provides an in-kernel fast path for packet 30 forwarding. It is complemented by a userspace daemon, ovs-vswitchd, 31 which is able to accept configuration from a variety of sources and 32 translate it into packet processing rules. 33 34 See http://openvswitch.org for more information and userspace 35 utilities. 36 37 To compile this code as a module, choose M here: the module will be 38 called openvswitch. 39 40 If unsure, say N. 41 42config OPENVSWITCH_GRE 43 tristate "Open vSwitch GRE tunneling support" 44 depends on OPENVSWITCH 45 depends on NET_IPGRE 46 default OPENVSWITCH 47 help 48 If you say Y here, then the Open vSwitch will be able create GRE 49 vport. 50 51 Say N to exclude this support and reduce the binary size. 52 53 If unsure, say Y. 54 55config OPENVSWITCH_VXLAN 56 tristate "Open vSwitch VXLAN tunneling support" 57 depends on OPENVSWITCH 58 depends on VXLAN 59 default OPENVSWITCH 60 help 61 If you say Y here, then the Open vSwitch will be able create vxlan vport. 62 63 Say N to exclude this support and reduce the binary size. 64 65 If unsure, say Y. 66 67config OPENVSWITCH_GENEVE 68 tristate "Open vSwitch Geneve tunneling support" 69 depends on OPENVSWITCH 70 depends on GENEVE 71 default OPENVSWITCH 72 help 73 If you say Y here, then the Open vSwitch will be able create geneve vport. 74 75 Say N to exclude this support and reduce the binary size. 76
