since when do you need udev for that?
you don't and you did not

that said from somebody which switched the way below eth0 and eth1 on a 
CentOS7 mini-PC acting as router months ago

[root at mail-gw:~]$ cat /etc/sysconfig/network-scripts/ifcfg-eth0
DEVICE=eth0
HWADDR=00:50:56:bd:35:50

ONBOOT=yes
ARPCHECK=no
BOOTPROTO=static
TYPE=Ethernet
MODE=Managed
IPADDR=**.**.**.**
NM_CONTROLLED=no
IPV6INIT=no
NETMASK=255.255.255.0
GATEWAY=**.**.**.**
