Subject: [PATCH net-next 3/5] neighbor: Remove state and flags arguments to neigh_del

From: David Ahern <[email-masked]>
Date: Tue, 11 Dec 2018 18:57:23 -0700

From: David Ahern <[email-masked]>

neigh_del now only has 1 caller, and the state and flags arguments
are both 0. Remove them and simplify neigh_del.
