Cloned from https://bugzilla.redhat.com/show_bug.cgi?id=1404521
Description of problem:

Satellite doesn't change pxelinux config files on tftp if the provisioning interface is different from the primary interface. The system gets build successfully but not able to boot because TFTP still has the config file for provisioning interface and not for primary.

Version-Release number of selected component (if applicable):
6.2.4
6.2.5

How reproducible:
100% with RHEV and bare metal machines

Steps to Reproduce:
1. Create a new host with two network interfaces and relevant MAC addresses
2. Choose one interface as primary and another one as provision
3. Build the host

Actual results:
The host will be provisioned but unable to boot from its primary interface. TFTP directory will has only PXE config for provision MAC address.

Expected results:
1. TFTP has the PXE config for primary interface
2. Host can boot correctly from its primary interface
