for_each_child_of_node performs an of_node_get on each iteration, so
a break out of the loop requires an of_node_put.
A simplified version of the semantic patch that fixes this problem is as
follows (http://coccinelle.lip6.fr):
// <smpl>
@@
local idexpression r.n;
expression r,e;
@@
for_each_child_of_node(r,n) {
...
(
of_node_put(n);
|
e = n
|
+ of_node_put(n);
? break;
)
...
}
... when != n
// </smpl>

Support for setting VF's corresponding BGX LMAC in internal
loopback mode. This mode can be used for verifying basic HW
functionality such as packet I/O, RX checksum validation,
CQ/RBDR interrupts, stats e.t.c. Useful when DUT has no external
network connectivity.
'loopback' mode can be enabled or disabled via ethtool.
Note: This feature is not supported when no of VFs enabled are
morethan no of physical interfaces i.e active BGX LMACs

Currently there is no way to get the MAC address in a firmware
independent manner, so set the MAC address of the device directly from
the ACPI tables.
The binding agrees with the proposed standard here:

Cortina phy does not have kernel driver and we don't attach
device with phy layer for intefaces like XFI, XLAUI etc,
Hence check for interface type before calling disconnect.

'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
