[net-next RFC v3 2/2] ixgbe: Get and display the notifications from changes of the Rx vxlan UDP port

[Jeff Kirsher <jeffrey.t.kirsher@intel.com>]

From: Joseph Gasparakis <joseph.gasparakis@intel.com>

This RFC patch showcases how drivers can use the changes in
"vxlan: Notify drivers for listening UDP port changes", and its
sole purpose is to help people test the changes introduced there.
This is not meant to be submitted for inclusion in the kernel.

    the main patch.
