Bug#968368: ifenslave: Option bond-master fails to add interface to bond

Good news! 
I fixed my setup and found a solution without patching ifenslave scripts.

This was a local configuration issue, automation applied an old configuration ( from stable release). 
According to ifenslave git history, team refactored code since 2.9, removed ifenslave binary and switched to iproute2 for low level work.
In my case, fix is - remove all configuration entries for slave devices and mention them only in the "slaves"  config option.

Without it, network-scripts try to configure interfaces with ifup and never hit the point to add interfaces to the bond device.

For more info I added debug output.

Unfortunately, patch does not work for me.
I have to install ifenslave 2.9 from stable release.
