From: Oliver Hartkopp socketcan@hartkopp.net

commit b4c2951a4833e66f1bbfe65ddcd4fdcdfafe5e8f upstream.

Picking up the patch from Serhey Popovych (commit 191cdb3822e5df6b3c8, "veth: Be more robust on network device creation when no attributes").

When the peer name attribute is not provided the former implementation tries to register the given device name twice ... which leads to -EEXIST. If only one device name is given apply an automatic generated and valid name for the peer.
