neigh: Allow for user space users of the neighbour table
Currently it is possible to do just about everything with the arp table from user space except treat an entry like you are using it. To that end implement and a flag NTF_USE that when set in a netwlink update request treats the neighbour table entry like the kernel does on the output path. This allows user space applications to share the kernel's arp cache. Signed-off-by:Eric Biederman <ebiederm@aristanetworks.com> Signed-off-by:
