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.

This fixes sparse messages like this:

drivers/net/ethernet/cavium/thunder/nicvf_main.c:1141:26: sparse: symbol
'nicvf_get_stats64' was not declared. Should it be static?

Also remove unused declarations

There are duplicate NODE_ID macro definitions. Move all of them to
nic.h for usage in nic and bgx driver and introduce nic_get_node_id()
helper function.

This patch also fixes 64bit mask which should have been ULL by
reworking the node calculation.

This patch adds support for the Cavium ThunderX network controller.
The driver is on the pci bus and thus requires the Thunder PCIe host
controller driver to be enabled.
