Description of problem:
Creating a bonded interface with 802.3ad in Satellite 6.1.3 does not deploy correctly. We expect to see a bond0 interface with a number of bond0.101, bond0.102 etc interfaces.

We try to create a bond0 which incorporates two devices, enp12s0f1 and enp22s0. Bonding options are deployed correctly. We use the MAC of the first interface, enp12s0f1 in the Sat 6 interface. When the host comes up after re-provisioning it sometimes creates a ifcfg-enp12s0f1.101 file or sometimes a ifcfg-.101 file.

Version-Release number of selected component (if applicable):
Satellite 6.1.3

Actual results:
The host comes up after re-provisioning it sometimes creates a ifcfg-enp12s0f1.101 file or sometimes a ifcfg-.101 file.

Expected results:
The host to have the configured bond options

Additional info:
We are wanting to deploy an OSP 7 environment using these network bonds so this will shortly be a blocker in doing so.

Customer worked around the issue by doing:
1) Making up a MAC address for the bond interface, something entirely bogus and then re-using that same MAC for the VLAN interfaces rendered us a kickstart that looks better.

Making up a MAC adress got us the bond created but then, adding VLAN:s on top of the bond fails as the snippet is doing a grep for the made-up MAC in the output of 'ip -l'

Next workaround was to acutally fix-up the broken config files for the VLANs

2) The workaround we used was to following patch against kickstart_network_setup

Do note that I doubt the workaround is generic enough to be used a generic solution
