To compile this driver as a module, choose M here. The module
will be called fm10k. MSI-X interrupt support is required

+ This allows one to create VXLAN virtual interfaces that provide

+ to tunnel virtual network infrastructure in virtualized environments.
+ Say Y here if you want to use Virtual eXtensible Local Area Network
