In addition to supporting a variety of features 24 expected in a traditional hardware switch, it enables fine-grained 25 programmatic extension and flow-based control of the network. This 26 control is useful in a wide variety of applications but is 27 particularly important in multi-server virtualization deployments, 28 which are often characterized by highly dynamic endpoints and the 29 need to maintain logical abstractions for multiple tenants. 30 31 The Open vSwitch datapath provides an in-kernel fast path for packet 32 forwarding. It is complemented by a userspace daemon, ovs-vswitchd, 33 which is able to accept configuration from a variety of sources and 34 translate it into packet processing rules. 35 36 See http://openvswitch.org for more information and userspace 37 utilities. 38 39 To compile this code as a module, choose M here: the module will be 40 called openvswitch. 41 42 If unsure, say N. 43 44config OPENVSWITCH_GRE 45 tristate "Open vSwitch GRE tunneling support" 46 depends on OPENVSWITCH 47 depends on NET_IPGRE 48 default OPENVSWITCH 49 help 50 If you say Y here, then the Open vSwitch will be able create GRE 51 vport. 52 53 Say N to exclude this support and reduce the binary size. 54 55 If unsure, say Y. 56 57config OPENVSWITCH_VXLAN 58 tristate "Open vSwitch VXLAN tunneling support" 59 depends on OPENVSWITCH 60 depends on VXLAN 61 default OPENVSWITCH 62 help 63 If you say Y here, then the Open vSwitch will be able create vxlan vport. 64 65 Say N to exclude this support and reduce the binary size. 66 67 If unsure, say Y. 68 69config OPENVSWITCH_GENEVE 70 tristate "Open vSwitch Geneve tunneling support" 71 depends on OPENVSWITCH 72 depends on GENEVE 73 default OPENVSWITCH 74 help 75 If you say Y here, then the Open vSwitch will be able create geneve vport. 76 77 Say N to exclude this support and reduce the binary size. 78
