In addition to supporting a variety of features 21 expected in a traditional hardware switch, it enables fine-grained 22 programmatic extension and flow-based control of the network. This 23 control is useful in a wide variety of applications but is 24 particularly important in multi-server virtualization deployments, 25 which are often characterized by highly dynamic endpoints and the 26 need to maintain logical abstractions for multiple tenants. 27 28 The Open vSwitch datapath provides an in-kernel fast path for packet 29 forwarding. It is complemented by a userspace daemon, ovs-vswitchd, 30 which is able to accept configuration from a variety of sources and 31 translate it into packet processing rules. 32 33 See http://openvswitch.org for more information and userspace 34 utilities. 35 36 To compile this code as a module, choose M here: the module will be 37 called openvswitch. 38 39 If unsure, say N. 40 41 config OPENVSWITCH_GRE 42 tristate "Open vSwitch GRE tunneling support" 43 depends on OPENVSWITCH 44 depends on NET_IPGRE 45 default OPENVSWITCH 46 help 47 If you say Y here, then the Open vSwitch will be able create GRE 48 vport. 49 50 Say N to exclude this support and reduce the binary size. 51 52 If unsure, say Y. 53 54 config OPENVSWITCH_VXLAN 55 tristate "Open vSwitch VXLAN tunneling support" 56 depends on OPENVSWITCH 57 depends on VXLAN 58 default OPENVSWITCH 59 help 60 If you say Y here, then the Open vSwitch will be able create vxlan vport. 61 62 Say N to exclude this support and reduce the binary size. 63 64 If unsure, say Y. 65 66 config OPENVSWITCH_GENEVE 67 tristate "Open vSwitch Geneve tunneling support" 68 depends on OPENVSWITCH 69 depends on GENEVE 70 default OPENVSWITCH 71 help 72 If you say Y here, then the Open vSwitch will be able create geneve vport. 73 74 Say N to exclude this support and reduce the binary size. 75
