Subject: [dpdk-dev] [RFC 07/24] vhost: move vhost_user_reconnect_init() into trans_af_unix.c
Date: Fri, 19 Jan 2018 13:44:27 +0000 [thread overview]
Message-ID: <20180119134444.24927-8-stefanha@redhat.com> (raw)
In-Reply-To: <20180119134444.24927-1-stefanha@redhat.com>
The socket reconnection code is highly specific to AF_UNIX, so move the
remaining pieces of it into trans_af_unix.c.
