Comment 13 for bug 1437375

There is an exception in /lib/udev/rules.d/75-persistent-net-generator.rules for ibmveth:

# ibmveth interfaces have stable locally administered MAC addresses
SUBSYSTEMS=="ibmveth", ENV{MATCHADDR}="$attr{address}"

This should override the issue related to locally administered mac addresses in this case. However, if we run:

udevadm monitor --e

and then:

echo "add" > /sys/class/net/eth0/uevent

We see:

KERNEL[622.903561] add /devices/vio/30000002/net/eth0 (net)

If I make this change to /lib/udev/rules.d/75-persistent-net-generator.rules, then I get a rule generated for ibmveth devices:
