Maybe one of the /sys attributes indicate, that it is a vlan interface?
Hmm... I tried DRIVERS!="8021q", then I got:
SUBSYSTEM=="net", ACTION=="add", DRIVERS!="8021q", ATTR{address}=="%s",
ATTR{type}=="1" NAME="eth0"
SUBSYSTEM=="net", ACTION=="add", DRIVERS!="8021q", ATTR{address}=="%s",
ATTR{type}=="1" NAME="eth0.2"
So, eth0 will be still renamed to eth0.2. :(
DEVPATH!="*/virtual/*" should help
The problem is not in udev rules themselves, the problem is we generate
two same lines for eth0 and eth0.2, even with DEVPATH!="*/virtual/*" we
will have:
SUBSYSTEM=="net", ACTION=="add", DEVPATH!="*/virtual/*",
ATTR{address}=="%s", ATTR{type}=="1" NAME="eth0"
SUBSYSTEM=="net", ACTION=="add", DEVPATH!="*/virtual/*",
ATTR{address}=="%s", ATTR{type}=="1" NAME="eth0.2"
eth0 will be still override. Thus, we should only generate one line for
eth0, and let ip/vconfig to name the eth0.2 upon eth0.
The reason why we have two lines is that I passed two ifname= cmdline,
one for eth0 and the other for eth0.2, this is required by ip=, all
interfaces in ip= should be passed in ifname= too.
Thanks!
