    net: Cavium: Fix MAC address setting in shutdown state · bd049a90
    Pavel Fedin 提交于
    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.
