[net-next,4/5] driver/net: enic: Exposing symbols for Cisco's low latency driver

This patch exposes symbols for usnic low latency driver that can be used to 
register and unregister vNics as well to traverse the resources on vNics.

Will usnic, or any other user of these symbols, be submitted for
inclusion in-tree as well?  It is generally expected that exported
functions do have an in-tree user.

Also, header files under drivers/ generally won't be included in
distribution -devel packages, so to support an out-of-tree module the
function prototypes would need to be included in a header under include/
(or else you have to repeat them and hope the types never change).
