I commit e099e86c
("tipc: add node_lock protection to link lookup function")
we are calling spin_lock(&node->lock) directly instead of indirectly
via the tipc_node_lock(node) function. However, tipc_node_lock() is
using spin_lock_bh(), not spin_lock(), something leading to
unbalanced usage in one place, and a smatch warning.

We fix this by consistently using tipc_node_lock()/unlock() in
in the places touched by the mentioned commit.

In commit 7d33939f
("tipc: delay delete of link when failover is needed") we
introduced a loop for finding and removing a link pointer
in an array. The removal is done after we have left the loop,
giving the impression that one may remove the wrong pointer
if no matching element is found.

This is not really a bug, since we know that there will always
be a matching element, but it looks wrong, and causes a smatch
warning.

We fix this loop with this commit.

Currently this always returns ENOBUFS, because the return value of

A more common failure is a duplicate name (EEXIST).  Propagate the real

Support for the Broadcom GENET driver

This patchset adds support for the Broadcom GENET Gigabit Ethernet MAC
controller. This controller is found on the Broadcom BCM7xxx Set Top Box
System-on-a-chips.

Changes since v4:
- add dependency on CONFIG_OF

Changes since v3:
- fixed Kconfig dependency on FIXED_PHY

Changes since v2:
- dropped the patch that adds an "internal" phy-mode

This method has been deprecated by the Skyhawk-R FW. Instead,
GET_PROFILE_CONFIG::port-desc must be used to query this configuration.

This patch also:
a) introduces a few macros to identify certain categories of multi-channel
configs
2) re-factors the be_cmd_set_profile_config() code to be able to read any kind
of desc (and not just the nic-desc.)
