[Impact]

Expose the IFLA_VXLAN_FAN_MAP constant via /proc and systcl, allowing user space (e.g. iproute2) to consume it at run-time

[Fix]

Apply the attached patch and rebuild the kernel

[How to test]

$ sudo modprobe vxlan

$ sudo sysctl -a | grep -i vxlan
net.fan.IFLA_VXLAN_FAN_MAP = 34
net.fan.vxlan = 4

$ cat /proc/sys/net/fan/IFLA_VXLAN_FAN_MAP
34

[Regression potential]

None, we are adding a new /proc / sysctl entry and no software depends on it ATM.
