Yes, this seems to be a problem with the ibft of the intel nic firmware. I do
not have the all FF FF problem, everything is correct, except for the
reverseusername, which is not surprising as the firmware BIOS setup interface
does not allow one to specify a reverseusername. But then I would expect the
reverse username sysfs attribute to be empty which it is not (which undoubtly
is a firmware bug).
