[PATCH net 0/2] neighbour: fix update of proxy neighbour

[Sabrina Dubroca <sd@queasysnail.net>]

While re-reading some "old" patches I ran into a small change of
behavior in commit dc2a27e524ac ("neighbour: Update pneigh_entry in
pneigh_create().").

The old behavior was not consistent between ->protocol and ->flags,
and didn't offer a way to clear protocol, so maybe it's better to
change that (7-years-old [1]) behavior. But then we should change
non-proxy neighbours as well to keep neigh/pneigh consistent.

  neighbour: restore protocol != 0 check in pneigh update
