[ovs-dev] Kernel Crash with VXLAN source code

Hi All,

I downloaded it and tried it for VXLAN. I am seeing the error "cannot
register vxlan protocol handler" and the tunnels doesn't get created. Looks
like the vxlan_socket_init() function is failing to create vxlan socket.

Any ideas on what is the issue?

Thanks & Regards,
Jagadish
