However, net_device_ops::ndo_set_vf_mac() may be called before\nVF is enabled to configure the MAC address of VF. If this is the case,\nenetc_pf_set_vf_mac() will access vf_state, resulting in access to a null\npointer. The simplified error log is as follows.\n\nroot@ls1028ardb:~# ip link set eno0 vf 1 mac 00:0c:e7:66:77:89\n[  173.543315] Unable to handle kernel NULL pointer dereference at virtual address
