Subject: iproute2: finish support for bonding attributes
Patch-mainline: v3.13.0?
Git-commit: 63d127b05dff4d21e8748b2ba9e0e6372897c383
References: fate#316940

Add support for bonding attributes just added to net-next.
On set, allow string or number value for enumerated attributes.
On show, use always use string value for attribute.
