on premise - mac address issue

[tamireran]

On mac address refresh (after import), the interfaces get wrong configuration.

/etc/sysconfig/network-scripts/ifcfg-eth0 - contains the previous mac address
/etc/udev/rules.d/70-persistant-net.rules - contains two interfaces: eth0 with old mac address, and eth1 with new mac address.

workaround:

1. update /etc/sysconfig/network-scripts/ifcfg-eth0 with new mac address
2. update /etc/udev/rules.d/70-persistant-net.rules - remove eth0 line and replace 'eth1' with 'eth0' (so the only line will be one with eth0 and new mac address)
