Revert "i40e: remove CONFIG_I40E_VXLAN"
This reverts commit 8fe269991aece394a7ed274f525d96c73f94109a. 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. Signed-off-by: Anjali Singhai Jain <anjali.singhai@intel.com> Acked-by: Jeff Kirsher <jeffrey.t.kirsher@intel.com> Signed-off-by: David S. Miller <davem@davemloft.net>
