In addition to supporting a variety of features 10ccb1352eSJesse Gross expected in a traditional hardware switch, it enables fine-grained 11ccb1352eSJesse Gross programmatic extension and flow-based control of the network. This 12ccb1352eSJesse Gross control is useful in a wide variety of applications but is 13ccb1352eSJesse Gross particularly important in multi-server virtualization deployments, 14ccb1352eSJesse Gross which are often characterized by highly dynamic endpoints and the 15ccb1352eSJesse Gross need to maintain logical abstractions for multiple tenants. 16ccb1352eSJesse Gross 17ccb1352eSJesse Gross The Open vSwitch datapath provides an in-kernel fast path for packet 18ccb1352eSJesse Gross forwarding. It is complemented by a userspace daemon, ovs-vswitchd, 19ccb1352eSJesse Gross which is able to accept configuration from a variety of sources and 20ccb1352eSJesse Gross translate it into packet processing rules. 21ccb1352eSJesse Gross 22ccb1352eSJesse Gross See http://openvswitch.org for more information and userspace 23ccb1352eSJesse Gross utilities. 24ccb1352eSJesse Gross 25ccb1352eSJesse Gross To compile this code as a module, choose M here: the module will be 26ccb1352eSJesse Gross called openvswitch. 27ccb1352eSJesse Gross 28ccb1352eSJesse Gross If unsure, say N. 29*fb825a55SPravin B Shelar 30*fb825a55SPravin B Shelarconfig OPENVSWITCH_GRE 31*fb825a55SPravin B Shelar bool "Open vSwitch GRE tunneling support" 32*fb825a55SPravin B Shelar depends on INET 33*fb825a55SPravin B Shelar depends on OPENVSWITCH 34*fb825a55SPravin B Shelar depends on NET_IPGRE_DEMUX && !(OPENVSWITCH=y && NET_IPGRE_DEMUX=m) 35*fb825a55SPravin B Shelar default y 36*fb825a55SPravin B Shelar ---help--- 37*fb825a55SPravin B Shelar If you say Y here, then the Open vSwitch will be able create GRE 38*fb825a55SPravin B Shelar vport. 39*fb825a55SPravin B Shelar 40*fb825a55SPravin B Shelar Say N to exclude this support and reduce the binary size. 41*fb825a55SPravin B Shelar 42*fb825a55SPravin B Shelar If unsure, say Y. 43
