[fedora-arm] Fedora-Minimal-armhfp-21-20140905-sda.raw.xz - Cubietruck ethernet not working

[Robert Moskowitz]

So tried:

# systemctl restart NetworkManager.service
[ 2811.279655] IPv6: ADDRCONF(NETDEV_UP): eth0: link is not ready
[root at localhost ~]# [ 2812.083261]  No MAC Management Counters available
[ 2812.100459] IPv6: ADDRCONF(NETDEV_UP): eth0: link is not ready

[ 2815.077039] IPv6: ADDRCONF(NETDEV_CHANGE): eth0: link becomes ready

# ip addr

group default
     link/loopback 00:00:00:00:00:00 brd 00:00:00:00:00:00
     inet 127.0.0.1/8 scope host lo
        valid_lft forever preferred_lft forever
     inet6 ::1/128 scope host
        valid_lft forever preferred_lft forever

     link/ether 86:80:43:3c:42:e1 brd ff:ff:ff:ff:ff:ff
     inet 208.83.67.186/28 brd 208.83.67.191 scope global dynamic eth0
        valid_lft 14180sec preferred_lft 14180sec

     inet6 fe80::8480:43ff:fe3c:42e1/64 scope link
        valid_lft forever preferred_lft forever

So I now have a working ethernet.  But I poweroff and poweron:

# ip addr
1: lo: <LOOPBACK,UP,LOWER_UP> mtu 65536 qdisc noqueue state UNKNOWN 
group default
     link/loopback 00:00:00:00:00:00 brd 00:00:00:00:00:00
     inet 127.0.0.1/8 scope host lo
        valid_lft forever preferred_lft forever
     inet6 ::1/128 scope host
        valid_lft forever preferred_lft forever
2: eth0: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc pfifo_fast 
state UP group default qlen 1000
     link/ether 5a:d5:ab:5f:50:63 brd ff:ff:ff:ff:ff:ff

Note the different MAC addr on new boot.

# systemctl restart NetworkManager.service

     inet6 fe80::58d5:abff:fe5f:5063/64 scope link
        valid_lft forever preferred_lft forever

Note the different IP address due to the different MACaddr.

Now I am part of the IEEE 802 MAC privacy study group where we are 
discussing randomizing MAC addresses for privacy reasons, but I keep 
exhausting my DHCP pool with each boot!  This test, I did not. There was 
NO DHCP query on poweron until I restarted NetworkManager.

What test next?
