Has anyone setup subinterfaces like eth0.10, etc? I have a tagged vlan and I can't get it to see the devices at all, all I ever get when trying to bring up the interface is:
device does not seem to be present delaying initialization
I had to modprobe 8021q manually, but it doesn't help anyways, even without tagging it doesn't see anything else except eth0 by itself.

I don't believe the smsc95xx driver supports vlans (from a grep of the driver code) I'm not sure if that's a hardware limitation or whether it's just not been implemented in the driver.
hmm, so then why won't normal subinterfaces work either then? Just taking a look over the code, I see what looks like vlan support as well:

ha! I got it to work. Had to be done manually, I have no idea why the ifcfg- scripts just won't take it, all it ever accepted was eth0:0 as a regular subinterface and thats it.
ip link add link eth0 name eth0.1 type vlan id 1 ip addr add 0.0.0.0 dev eth0.1 ip link set eth0.1 up dhclient eth0.1

And... no one else on here knew that...

Likely nobody has a need to use vlans on the device. I certainly haven't tested it.
