OK i reply to myself...
I've found that udev dont generate file in /etc/udev/rules.d anymore.
The naming process is based on hardware slot.
To make the naming persistent and define the ordering, you need to write the file you need like /etc/udev/rules.d/70-persistent-net.rules:
# PCI device 0x8086:0x108c (e1000e) (custom name provided by external tool)
SUBSYSTEM=="net", ACTION=="add", DRIVERS=="?*", ATTR{address}=="00:50:56:99:25:a8", ATTR{type}=="1", KERNEL=="eth*", NAME="eth0"
SUBSYSTEM=="net", ACTION=="add", DRIVERS=="?*", ATTR{address}=="00:50:56:99:06:8d", ATTR{type}=="1", KERNEL=="eth*", NAME="eth1"
SUBSYSTEM=="net", ACTION=="add", DRIVERS=="?*", ATTR{address}=="00:50:56:99:5c:7b", ATTR{type}=="1", KERNEL=="eth*", NAME="eth2"
SUBSYSTEM=="net", ACTION=="add", DRIVERS=="?*", ATTR{address}=="00:50:56:99:0a:36", ATTR{type}=="1", KERNEL=="eth*", NAME="eth3"
SUBSYSTEM=="net", ACTION=="add", DRIVERS=="?*", ATTR{address}=="00:50:56:99:07:5f", ATTR{type}=="1", KERNEL=="eth*", NAME="eth4"
SUBSYSTEM=="net", ACTION=="add", DRIVERS=="?*", ATTR{address}=="00:50:56:99:35:71", ATTR{type}=="1", KERNEL=="eth*", NAME="eth5"
SUBSYSTEM=="net", ACTION=="add", DRIVERS=="?*", ATTR{address}=="00:50:56:99:15:aa", ATTR{type}=="1", KERNEL=="eth*", NAME="eth6"
SUBSYSTEM=="net", ACTION=="add", DRIVERS=="?*", ATTR{address}=="00:50:56:99:7c:71", ATTR{type}=="1", KERNEL=="eth*", NAME="eth7"
that's all.
