Subject: [PATCH RFC/RFT net-next 02/17] net/neigh: export neigh_find_table
Date: Tue, 17 Jul 2018 05:06:36 -0700
Message-ID: <20180717120651.15748-3-dsahern@kernel.org> (raw)
In-Reply-To: <20180717120651.15748-1-dsahern@kernel.org>

From: David Ahern <dsahern@gmail.com>

neighbor code already has an API for access to neighbor caches by
address family. Export it for use by networking code. Add the
namespace as an input arg and make family a u8 versus an int (all
existing callers pass ndm_family which is a u8).
