rewrite vxlan to better fit the current kernel infrastructure.
the big change is removing the integration with and reliance on bridge(4) for learning vxlan endpoints. we have the etherbridge layer now (which is used by veb, nvgre, bpe, etc) so vxlan can operate independently of bridge(4) (or any other driver) while still dynamically learning about other endpoints. vxlan now uses the udp socket upcall mechanism to receive packets. this means it actually creates and binds udp sockets to use rather adding code in the udp layer for stealing packets from the udp layer. i think it's also important to note that this adds loop prevention to the code. this stops a vxlan interface being used to transmit a packet that was encapsulated in itself. i want to clear this out of my tree where it's been sitting for nearly a year. noone seems too concerned with the change either way. ok claudio@
