Subject: [PATCH] iproute2: finish support for bonding attributes
Bugzilla: https://bugzilla.redhat.com/show_bug.cgi?id=1269528
Upstream Status: iproute2.git commit 63d127b05dff4
commit 63d127b05dff4d21e8748b2ba9e0e6372897c383
Author: sfeldma@cumulusnetworks.com <sfeldma@cumulusnetworks.com>

iproute2: finish support for bonding attributes
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.
