The current code writes the PME enabled bit in PCI config space which is
wrong. This was needed for pre-release hardware, and was not removed from
the driver. Also, we need to clear the WUS (wake up status) after we
resume. Otherwise we can't wake for the same event again since it's still
asserted in the hardware. Plus, the multicast lists were being written
improperly, causing multicast WoL to fail.

Pointed out by Sean E. Millichamp.
Quote from Documentation/networking/bonding.txt:
"Note that when a bonding interface has no active links, the
driver will immediately reuse the first link that goes up, even if the
updelay parameter has been specified (the updelay is ignored in this
case). If there are slave interfaces waiting for the updelay timeout
to expire, the interface that first went into that state will be
immediately reused. This reduces down time of the network if the
value of updelay has been overestimated, and since this occurs only in
cases with no connectivity, there is no additional penalty for
ignoring the updelay."
This patch actually changes the behaviour in this way.

Modules are not supposed to use any of the *_initcall*() hooks as
the entry point. fsl_pq_mdio.c was using subsys_initcall_sync()
instead of module_init() to guarantee that the MDIO bus was initialized
before the Ethernet driver goes looking for the phy. However, the recent
OF helpers rework happens to also make sure PHY connection is deferred to
.open time, so using an initcall is no longer necessary.
This patch replaces the initcall with a more traditional an accepted
module_init() call.

This patch adds support for the Xilinx ll_temac 10/100/1000 Ethernet
device. The ll_temac ipcore is typically used on Xilinx Virtex and
Spartan designs attached to either a PowerPC 4xx or Microblaze
processor.
At the present moment, this driver only works with Virtex5 PowerPC
designs because it assumes DCR is used to access the DMA registers.
However, the low level access to DMA registers is abstracted and
it should be easy to adapt for the other implementations.
I'm posting this driver now as an RFC. There are still some things that
need to be tightened up, but it does appear to be stable.

- Cleanup handling of phy_map[] entries; they are already NULLed when

to clear them out when unregistering.
- Split phy_device registration out into a new function so that the

This patch adds interrupt statistics report to debugfs, this can help to
understand number of interrupts happened which including HW/SW error for
easier and better debugging.

This patch fixes a bug introduced by commit "iwlwifi: adding MIMO3 support
in rate scaling". We should not set the dual_stream_ant_msk (for 2x2 MIMO)
when using a 3x3 rate, this will cause a SYSASSERT in uCode.
Note: there is no triple_stream_ant_msk, because all three antennas are used.

libertas: add support for Marvell SD8688 chip
Use RxPD->pkt_ptr to locate eth803 header in the packet
received since SD8688/v10 firmware allows a gap between
RxPD and eth803 header.
Set SDIO block size to 256 for CMD53.
The maximum block size for SD8688 WLAN function is set
to 512 in TPLFE_MAX_BLK_SIZE. But using 512 as block size
results upto 2K bytes data (4 blocks) being transferred
and causes buffer overflow in firmware.
Both changes above are backward compatible with earlier
firmware versions for SD8385/SD8686.
The SDIO_DEVICE_IDs for SD8688 chip are added in
include/linux/mmc/sdio_ids.h
