* openvswitch: Add SCTP supportJoe Stringer2013-08-261-0/+1
| | | | | | | | | | | | | | | This patch adds support for rewriting SCTP src,dst ports similar to the functionality already available for TCP/UDP. Rewriting SCTP ports is expensive due to double-recalculation of the SCTP checksums; this is performed to ensure that packets traversing OVS with invalid checksums will continue to the destination with any checksum corruption intact.

* openvswitch: Add vxlan tunneling support.Pravin B Shelar2013-08-201-0/+13
| | | | | | | | | | Following patch adds vxlan vport type for openvswitch using vxlan api. So now there is vxlan dependency for openvswitch.

* openvswitch: Add Kconfig dependency on GRE-DEMUX.Pravin B Shelar2013-07-011-2/+14
| | | | | | | | | | | | | Openvswitch uses function from NET_IPGRE_DEMUX module. Add Kconfig dependency to fix following compilation errors: http://marc.info/?l=linux-netdev&m=137244035226634 CC: Jesse Gross <jesse@nicira.com> Reported-by: Randy Dunlap <rdunlap@infradead.org> Signed-off-by: Pravin Shelar <pshelar@nicira.com> Acked-by: Randy Dunlap <rdunlap@infradead.org> Acked-by: Jesse Gross <jesse@nicira.com> Signed-off-by: David S.

* openvswitch: Add gre tunnel support.Pravin B Shelar2013-06-191-0/+2
| | | | | | | | | | Add gre vport implementation. Most of gre protocol processing is pushed to gre module. It make use of gre demultiplexer therefore it can co-exist with linux device based gre tunnels.

* net: Add Open vSwitch kernel components.Jesse Gross2011-12-031-0/+28
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. Signed-off-by: Jesse Gross <jesse@nicira.com>
