[dpdk-dev] net/bonding: don't early mark eth device as bonded
Checks
Commit Message
From: "Charles (Chas) Williams" <ciwillia@mail.eng.vyatta.net>
bonding immediately marks the incoming eth device as bonded and doesn't
clear this in later error paths. Delay marking the dev until we are
certain that we are going to add this eth device to the bond group.
