Alexander V. Chernikov	25c2dd2f2c	netlink: return optional metadata with the operation result. ... Some operations like interface creation may need to return metadata - in this case, interface name - back to the caller if the operation is successful. This change implements attaching an `NLMSGERR_ATTR_COOKIE` nla to the operation reply message via `nlmsg_report_cookie()`. Additionally, on successful interface creation, interface index and interface name are returned in the `IFLA_NEW_IFINDEX` and `IFLA_IFNAME TLVs, encapsulated in the `NLMSGERR_ATTR_COOKIE`.
