## Open vSwitch# config OPENVSWITCH	tristate "Open vSwitch"	select LIBCRC32C	---help---	  Open vSwitch is a multilayer Ethernet switch targeted at virtualized	  environments.  In addition to supporting a variety of features	  expected in a traditional hardware switch, it enables fine-grained	  programmatic extension and flow-based control of the network.  This	  control is useful in a wide variety of applications but is	  particularly important in multi-server virtualization deployments,	  which are often characterized by highly dynamic endpoints and the	  need to maintain logical abstractions for multiple tenants. 	  The Open vSwitch datapath provides an in-kernel fast path for packet	  forwarding.  It is complemented by a userspace daemon, ovs-vswitchd,	  which is able to accept configuration from a variety of sources and	  translate it into packet processing rules. 	  See http://openvswitch.org for more information and userspace	  utilities. 	  To compile this code as a module, choose M here: the module will be	  called openvswitch. 	  If unsure, say N. config OPENVSWITCH_GRE	bool "Open vSwitch GRE tunneling support"	depends on INET	depends on OPENVSWITCH	depends on NET_IPGRE_DEMUX && !(OPENVSWITCH=y && NET_IPGRE_DEMUX=m)	default y	---help---	  If you say Y here, then the Open vSwitch will be able create GRE	  vport. 	  Say N to exclude this support and reduce the binary size. 	  If unsure, say Y. config OPENVSWITCH_VXLAN	bool "Open vSwitch VXLAN tunneling support"	depends on INET	depends on OPENVSWITCH	depends on VXLAN && !(OPENVSWITCH=y && VXLAN=m)	default y	---help---	  If you say Y here, then the Open vSwitch will be able create vxlan vport. 	  Say N to exclude this support and reduce the binary size. 	  If unsure, say Y.
