[fedora-arm] raspberry pi with F25

[solarflow99]

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


# ip -d link show eth0.1
3: ***@eth0: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc noqueue

# ip addr show 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.
