File datapath-Add-support-for-Linux-3.12.patch of Package openvswitch (Revision 6243ff43f12eca74e530496b069dda82)

Currently displaying revision 6243ff43f12eca74e530496b069dda82 , Show latest

Bump kernel support for datapath module to include 3.12.

Make use of native vxlan kernel module for Linux >= 3.12 or if
the kernel in use supports the required vxlan functions.

Make use of native iptunnels capability for Linux >= 3.12.

Note: ipv6 enablement with vxlan is not supported by this change.
