Currently, we don't rename the upper/lower_ifc symlinks in
/sys/class/net/*/ , which might result stale/duplicate links/names.
Fix this by adding netdev_adjacent_rename_links(dev, oldname) which renames
all the upper/lower interface's links to dev from the upper/lower_oldname
to the new name.
We don't need a rollback because only we control these symlinks and if we
fail to rename them - sysfs will anyway complain.

Linux bonding driver provides a method for aggregating multiple network
interface controllers (NICs) into a single logical bonded interface of
two or more so called (NIC) slaves. Slave selection for outgoing traffic
is done according to the transmit hash policy, which may be changed from
the default simple XOR policy via the xmit_hash_policy option. This
selection algorithm in Linux bonding driver is based on software.
The QorIQ Data Path Acceleration Architecture (DPAA) is a comprehensive
architecture which integrates all aspects of packet processing in the
SoC, addressing issues and requirements resulting from the multicore
nature of QorIQ SoCs. The DPAA includes Cores, Network and packet I/O,
Hardware offload accelerators. Hardware offload accelerators include
FMan/BMan/QMan and etc.
Offline port is one of FMan elements, which supports (Parse, Classify,
Distribute) PCD function on frames extracted frame descriptor (FD).
Offline port also can inspect traffic, split it into FQs on ingress, and
send traffic from the FQs to the interface on egress by the PCD function.
These patches are enhancing Linux kernel LAG (Link Aggregation) with
Freescale DPAA value added. The main idea is to utilize offline ports
with PCD function to help to distribute outgoing traffics, including
outgoing slaves device searching and selection. In another world,
patches are using CRC-64 based hashing of Keygen/scheme and the parser
result of outgoing frames header information to distribute outgoing
frames.
Beside of above, after integration this HW based LAG with Freescale
CEETMQos, these two features can support hardware based Qos for bundles
links rather than individual links.
These patches mainly include 2 parts:
'glue logic' and 'kernel space PCD'.
The glue logic first probes all available offline ports information via
reading dts, including tx fqid/default fqid/errors fqid, pcd fqs, other
private data pointer of offline ports for future reusing. The glue logic
also creates frames from skb and then sends these frames to offline port
directly, this offline port will continue to distribution frames from
the PCD FQs to the slave interface on egress by the PCD function, rather
than select slave device by CPU, neither make slave device driver create
frame from skb, nor make slave devices driver send frames.
These patches are supporting the mapping among offline ports and
available bundles at run-time. PCD based outgoing traffic distribution
can be enabled or disabled at run-time by sysfs interface in patches.
To do:
1. PCD policy L23/L34 have not been veryfied.
2. offline port buffer pool/buffer layout will be enhanced.
3. software based L4 csum for now, offline port based L4 csum need be fixed.
To test this HW based LAG after booting up Linux:
cd /sys/class/net/bond0/bonding/
echo 4 >mode
cat offline_ports
echo fman0-oh@1 > oh_needed_for_hw_distribution
cat oh_needed_for_hw_distribution

This framework enables eTSEC's filer and the FGPI Rx
interrupt (Filer General Purpose Interrupt) as a wakeup
source event.
Upon entering suspend state, the eTSEC filer can be
programmed with various match rules for the Rx packets.
For example, the rules could be matching incoming unicast
or arp packets. If a packet matches one of the rules, it
will be enqueued in the Rx ring and a FGPI interrupt will
be generated by the filer to wakeup the system. The packet
types not matching the rules will be dropped.
The rules need to be added as filer scripts inside
gfar_filer_config_wol() to implement different WOL
capabilities.
The "fsl,wake-on-filer" DT binding limits this
capability to certain platforms only.

The two fundamental things I know we can not allow are:
- A shared signal queue aka CLONE_THREAD. Because we compute the pid
and uid of the signal when we place it in the queue.
- Changing the pid and by extention pid_namespace of an existing
process.
From a parents perspective there is nothing special about the pid
namespace, to deny CLONE_PARENT, because the parent simply won't know or
care.
From the childs perspective all that is special really are shared signal
queues.
User mode threading with CLONE_PARENT|CLONE_VM|CLONE_SIGHAND and tasks
in different pid namespaces is almost certainly going to break because
it is complicated. But shared signal handlers can look at per thread
information to know which pid namespace a process is in, so I don't know
of any reason not to support CLONE_PARENT|CLONE_VM|CLONE_SIGHAND threads
at the kernel level. It would be absolutely stupid to implement but
that is a different thing.
So hmm.
Because it can do no harm, and because it is a regression let's remove
the CLONE_PARENT check and send it stable.

Use device flag IFF_LIVE_ADDR_CHANGE to signal that
the device supports changing the hardware address when
the device is running.
This allows eth_mac_addr() to change the mac address
also when the network device's interface is open.
This capability is required by certain applications,
like bonding mode 6 (Adaptive Load Balancing).

This patch adds suspend resume functions for Freescale DMA driver.
.prepare callback is used to stop further descriptors from being added into the
pending queue, and also issue pending queues into execution if there is any.
.suspend callback makes sure all the pending jobs are cleaned up and all the
channels are idle, and save the mode registers.
.resume callback re-initializes the channels by restore the mode registers.

Change the pme error interrupt handler to be per-CPU to avoid a warning
("Cannot set affinity for irq") when entering suspend-to-ram state.
Added IRQF_PERCPU flag.
While sending frames to the PME device, this device can return a serious error.
Added logic to properly handle this scenario. If this happens while reading
the pme database, upon resume the resulting database will not be restored.
The size of the confidence table was incorrect for a specific version of pme.

When power is removed from the pme device, all its internal state is lost.
The suspend() function saves all necessary state in order to later resume
the device. The resume() function "writes" back the previously saved state.
The functionality is implemented as part of the pme ctrl plane device.
The state the requires saving is CCSR registers and internal SRAM memory.

In order for supported SoCs to enter deepsleep the QBMan ip blocks must not
have any pending interrupt status bits set in the Portals.
Therefore, in the pm callbacks for each portal, save the isdr, and clear the isr.
On the resume side, reset the save isdr.
Also fix the buffer pool depletion notification in all bman portals.
The default value is to notify them. This is an issue for unused portals, as
the portal will have the corresponding isr bit set and will prevent deepsleep
for occuring.
The unused portals need to have their ISDR and ISR cleared in order for
the qman block to enter idle state.
Also re-added the setting of ISDR clear ISR for the qbman ccsr block.

T104x has deep sleep feature, which can switch off most parts of
the SoC when it is in deep sleep mode. This way, it becomes more
energy-efficient.
The DDR controller will also be powered off in deep sleep. Therefore,
the last stage (the latter part of fsl_dp_enter_low) will run without DDR
access. This piece of code and related TLBs are prefetched in advance.
Due to the different initialization code between 32-bit and 64-bit, they
have seperate resume entry and precedure.
The feature supports 32-bit and 64-bit kernel mode.
