Description Thomas Haller 2016-08-30 16:13:21 UTC
Some buggy drivers either
 - signal success on the netlink message to change the MAC address, but the
   address only actually change the address a moment later.
 - fail the netlink command with ENFILE but the address actually changes.

See for example upstream https://bugzilla.gnome.org/show_bug.cgi?id=770456 or bug 1371478.

this is fixed upstream with

These workaround should be backported to rhel-7.3
