> This bug pops up with NetworkManager on Fedora 21. NetworkManager tends to
> stop the interface (nicvf_stop() is called) before changing settings. In
> stopped state MAC cannot be sent to a PF. However, when the interface is
> restarted (nicvf_open() is called), we ping the PF using NIC_MBOX_MSG_READY
> message, and the PF replies back with old MAC address, overriding what we had
> after MAC setting from userspace. As a result, we cannot set MAC address using
> NetworkManager.
> 
> This patch introduces special tracking of MAC change in stopped state so that
> the correct new MAC address is sent to a PF when interface is reopen.
