Network Interfaces being renamed

[MACscr]

OK, so I have to rename two of my interfaces on my trusty servers because of the how the mlxn_en drivers work for for my 10gb nics. It gets confusing because they are named eth0 and eth1, while my main onboard nics are em1 and em2 and i need some consistency amongst my servers. Any, im using the following to rename them:

root@stor1:/proc/net/vlan# cat /etc/udev/rules.d/70-persistent-net.rulesSUBSYSTEM=="net", ACTION=="add", ATTR{address}=="00:a0:d1:ed:42:c9", NAME="em2"
SUBSYSTEM=="net", ACTION=="add", ATTR{address}=="00:a0:d1:ed:42:c8", NAME="em1"
SUBSYSTEM=="net", ACTION=="add", ATTR{address}=="00:1e:0b:4c:69:79", NAME="mlx1"
SUBSYSTEM=="net", ACTION=="add", ATTR{address}=="00:1e:0b:4c:69:7a", NAME="mlx2"

Which typically works fine, but having an issue occasionally with it and vlans:

root@stor1:/proc/net/vlan# cat /proc/net/vlan/config
VLAN Dev name	 | VLAN ID
Name-Type: VLAN_NAME_TYPE_PLUS_VID_NO_PAD
rename8        | 10  | bond0
rename9        | 20  | bond0

Maybe they arent even related, but I have no idea why the vlans are no longer coming up and since it says rename, it made me think of the some of the interfaces that are part of that bond. Here is some more info:

root@stor1:/proc/net/vlan# cat /etc/network/interfaces

The switch to predictable interfaces names currently has issues, particularly on Ubuntu Server edition.
In the end, the only way I could get predictable repeatable results for all kernels was to have this on my /etc/default/grub line:

GRUB_CMDLINE_LINUX_DEFAULT="net.ifnames=1 biosdevname=0"

Yes, but my interfaces are being renamed correctly. I dont get why the vlans are behaving this way.

Ah, i just had to add DRIVERS=="?*" to my udev rules and it worked. woo hoo
