Revert "i40e: remove CONFIG_I40E_VXLAN"

Browse Source 
This reverts commit 8fe269991a.
The case where VXLAN is a module and i40e driver is inbuilt
will not be handled properly with this change since i40e
will have an undefined symbol vxlan_get_rx_port in it.

v2: Add a signed-off-by.

To compile this driver as a module, choose M here. The module
will be called i40e.

---help---
This allows one to create VXLAN virtual interfaces that provide
Layer 2 Networks over Layer 3 Networks. VXLAN is often used
to tunnel virtual network infrastructure in virtualized environments.
Say Y here if you want to use Virtual eXtensible Local Area Network
(VXLAN) in the driver.
