This function will try to determine the mac address via the devicetree,
or via an architecture-specific method (e.g. a PROM on SPARC).
The SPARC-specific code in this driver (#ifdef SPARC) did exactly this,
and is therefore removed.
Note that you can now specify the tg3 mac address via the devicetree,
on any platform, not just SPARC:
Devicetree example:
(see Documentation/devicetree/bindings/pci/pci.txt)
&pcie {
host@0 {
#address-cells = <3>;
#size-cells = <2>;
reg = <0 0 0 0 0>;
bcm5778: bcm5778@0 {
reg = <0 0 0 0 0>;
mac-address = [CA 11 AB 1E 10 01];
};
};
};

net: bcmgenet: fix aborted suspend
It is not enough to return an error code from the driver suspend
routine. The driver must also restore the device functionality.
This commit corrects the issue introduced by commit 0db55093b5
("net: bcmgenet: return correct value 'ret' from bcmgenet_power_down")
by calling the driver resume function if the suspend function returns
an error.

If an error occurs during suspension of the driver the driver should
restore the hardware configuration and return an error to force the
system to resume.

This patch adds vport alive state checking support, in order

net/ncsi: Allow enabling multiple packages & channels
This series extends the NCSI driver to configure multiple packages
and/or channels simultaneously. Since the RFC series this includes a few
extra changes to fix areas in the driver that either made this harder or
were roadblocks due to deviations from the NCSI specification.
Patches 1 & 2 fix two issues where the driver made assumptions about the
capabilities of the NCSI topology.
Patches 3 & 4 change some internal semantics slightly to make multi-mode
easier.
Patch 5 introduces a cleaner way of reconfiguring the NCSI configuration
and keeping track of channel states.
Patch 6 implements the main multi-package/multi-channel configuration,
configured via the Netlink interface.
Readers who have an interesting NCSI setup - especially multi-package
with HWA - please test! I think I've covered all permutations but I
don't have infinite hardware to test on.
Changes in v2:
- Updated use of the channel lock in ncsi_reset_dev(), making the
channel invisible and leaving the monitor check to
ncsi_stop_channel_monitor().
- Fixed ncsi_channel_is_tx() to consider the state of channels in other
packages.
Changes in v3:
- Fixed bisectability bug in patch 1
- Consider channels on all packages in a few places when multi-package
is enabled.
- Avoid doubling up reset operations, and check the current driver state
before reset to let any running operations complete.
- Reorganise the LSC handler slightly to avoid enabling Tx twice.
Changes in v4:
- Fix failover in the single-channel case
- Better handle ncsi_reset_dev() entry during a current config/suspend
operation.
====================

This patch extends the ncsi-netlink interface with two new commands and
three new attributes to configure multiple packages and/or channels at
once, and configure specific failover modes.
NCSI_CMD_SET_PACKAGE mask and NCSI_CMD_SET_CHANNEL_MASK set a whitelist
of packages or channels allowed to be configured with the
NCSI_ATTR_PACKAGE_MASK and NCSI_ATTR_CHANNEL_MASK attributes
respectively. If one of these whitelists is set only packages or
channels matching the whitelist are considered for the channel queue in
ncsi_choose_active_channel().
These commands may also use the NCSI_ATTR_MULTI_FLAG to signal that
multiple packages or channels may be configured simultaneously. NCSI
hardware arbitration (HWA) must be available in order to enable
multi-package mode. Multi-channel mode is always available.
If the NCSI_ATTR_CHANNEL_ID attribute is present in the
NCSI_CMD_SET_CHANNEL_MASK command the it sets the preferred channel as
with the NCSI_CMD_SET_INTERFACE command. The combination of preferred
channel and channel whitelist defines a primary channel and the allowed
failover channels.
If the NCSI_ATTR_MULTI_FLAG attribute is also present then the preferred
channel is configured for Tx/Rx and the other channels are enabled only
for Rx.

When the NCSI driver is stopped with ncsi_stop_dev() the channel
monitors are stopped and the state set to "inactive". However the
channels are still configured and active from the perspective of the
network controller. We should suspend each active channel but in the
context of ncsi_stop_dev() the transmit queue has been or is about to be
stopped so we won't have time to do so.
Instead when ncsi_start_dev() is called if the NCSI topology has already
been probed then call ncsi_reset_dev() to suspend any channels that were
previously active. This resets the network controller to a known state,
provides an up to date view of channel link state, and makes sure that
mode flags such as NCSI_MODE_TX_ENABLE are properly reset.
In addition to ncsi_start_dev() use ncsi_reset_dev() in ncsi-netlink.c
to update the channel configuration more cleanly.

The concepts of a channel being 'active' and it having link are slightly
muddled in the NCSI driver. Tweak this slightly so that
NCSI_CHANNEL_ACTIVE represents a channel that has been configured and
enabled, and NCSI_CHANNEL_INACTIVE represents a de-configured channel.
This distinction is important because a channel can be 'active' but have
its link down; in this case the channel may still need to be configured
so that it may receive AEN link-state-change packets.

When a package is deselected all channels of that package cease
communication. If there are other channels active on the package of the
suspended channel this will disable them as well, so only send a
deselect-package command if no other channels are active.

Currently the NCSI driver sends a select-package command to all possible
packages simultaneously to discover what packages are available. However
at this stage in the probe process the driver does not know if
hardware arbitration is available: if it isn't then this process could
cause collisions on the RMII bus when packages try to respond.
Update the probe loop to probe each package one by one, and once
complete check if HWA is universally supported.
