In addition to supporting a variety of features 11ccb1352eSJesse Gross expected in a traditional hardware switch, it enables fine-grained 12ccb1352eSJesse Gross programmatic extension and flow-based control of the network. This 13ccb1352eSJesse Gross control is useful in a wide variety of applications but is 14ccb1352eSJesse Gross particularly important in multi-server virtualization deployments, 15ccb1352eSJesse Gross which are often characterized by highly dynamic endpoints and the 16ccb1352eSJesse Gross need to maintain logical abstractions for multiple tenants. 17ccb1352eSJesse Gross 18ccb1352eSJesse Gross The Open vSwitch datapath provides an in-kernel fast path for packet 19ccb1352eSJesse Gross forwarding. It is complemented by a userspace daemon, ovs-vswitchd, 20ccb1352eSJesse Gross which is able to accept configuration from a variety of sources and 21ccb1352eSJesse Gross translate it into packet processing rules. 22ccb1352eSJesse Gross 23ccb1352eSJesse Gross See http://openvswitch.org for more information and userspace 24ccb1352eSJesse Gross utilities. 25ccb1352eSJesse Gross 26ccb1352eSJesse Gross To compile this code as a module, choose M here: the module will be 27ccb1352eSJesse Gross called openvswitch. 28ccb1352eSJesse Gross 29ccb1352eSJesse Gross If unsure, say N. 30fb825a55SPravin B Shelar 31fb825a55SPravin B Shelarconfig OPENVSWITCH_GRE 32fb825a55SPravin B Shelar bool "Open vSwitch GRE tunneling support" 33fb825a55SPravin B Shelar depends on INET 34fb825a55SPravin B Shelar depends on OPENVSWITCH 35fb825a55SPravin B Shelar depends on NET_IPGRE_DEMUX && !(OPENVSWITCH=y && NET_IPGRE_DEMUX=m) 36fb825a55SPravin B Shelar default y 37fb825a55SPravin B Shelar ---help--- 38fb825a55SPravin B Shelar If you say Y here, then the Open vSwitch will be able create GRE 39fb825a55SPravin B Shelar vport. 40fb825a55SPravin B Shelar 41fb825a55SPravin B Shelar Say N to exclude this support and reduce the binary size. 42fb825a55SPravin B Shelar 43fb825a55SPravin B Shelar If unsure, say Y. 4458264848SPravin B Shelar 4558264848SPravin B Shelarconfig OPENVSWITCH_VXLAN 4658264848SPravin B Shelar bool "Open vSwitch VXLAN tunneling support" 4758264848SPravin B Shelar depends on INET 4858264848SPravin B Shelar depends on OPENVSWITCH 4958264848SPravin B Shelar depends on VXLAN && !(OPENVSWITCH=y && VXLAN=m) 5058264848SPravin B Shelar default y 5158264848SPravin B Shelar ---help--- 5258264848SPravin B Shelar If you say Y here, then the Open vSwitch will be able create vxlan vport. 5358264848SPravin B Shelar 5458264848SPravin B Shelar Say N to exclude this support and reduce the binary size. 5558264848SPravin B Shelar 5658264848SPravin B Shelar If unsure, say Y. 57
