Subject: [PATCH] openvswitch: use -EEXIST as return error to be more precise
Date: Tue, 28 May 2013 14:31:16 +0800	[thread overview]
Message-ID: <1369722676-7898-1-git-send-email-fan.du@windriver.com> (raw)

ovs_vport_cmd_new create a new vport with port num specified by user.
when this port num is already occupied, it's more clear to return
-EEXIST as the reason than -EBUSY.
