You are correct, it is related.
VDSM takes over the ifcfg configuration of the interfaces it manages and
writes its own settings (overwriting the existing config after backing it
up).
At the moment, we do not support the LINKDELAY option.

As an workaround, you could use a VDSM before_ifcfg_write hook to add this
parameter for the specific nic.

Please open a bug on this so we can track it.

Thanks,
Edy.
