This change adds the first network driver for the tile architecture,
supporting the on-chip XGBE and GBE shims.
The infrastructure is present for the TILE-Gx networking drivers (another
three source files in the new directory) but for now the the actual
tilegx sources are waiting on releasing hardware to initial customers.
Note that arch/tile/include/hv/* are "upstream" headers from the
Tilera hypervisor and will probably benefit less from LKML review.

This patch fixes the following section mismatch warning:
WARNING: drivers/net/can/pch_can.o(.data+0x18):
Section mismatch in reference from the variable pch_can_pcidev
to the variable .devinit.rodata:pch_pci_tbl
The variable pch_can_pcidev references
the variable __devinitconst pch_pci_tbl
This is actually a false positive which is fixed by giving the offending
variable a whitelisted name, it's renamed to "pch_can_pci_driver".
This makes sense because the variable is of the type "struct pci_driver".

The marvell 88ec048's official part number is 88e1318s. This patch renames
definitions in the driver to reflect this.
In addition, a minor bug fix has been added to write back the MSCR1 register
value properly.

For the SD8686, we cannot rely on the scratch register to read the firmware
load status, because the same register is used for storing RX packet length.
Broaden the check to account for this.
The module can now be unloaded/reloaded successfully.
Based on the implementation from libertas_tf.

The index variable to access the rate flags should be obtained from the
inner loop counter which corresponds to the rate table structure.This
fixes the invalid rate selection i.e when the supported basic rate is
invalid on a particular band and also the following warning message.
Thanks to Raj for finding this out.

This patch enables and disables the rx and tx bits in the MAC control reg
by using a single write operation.
This also solves a possible problem (spotted on SPEAr platforms) at 10Mbps
where two consecutive writes to a MAC control register can take more than
4 phy_clk cycles.

Along the same lines as "cxgb4: fix crash due to manipulating queues
before registration" (8f6d9f40476895571df039b6f1f5230ec7faebad), before
commit "net: allocate tx queues in register_netdevice"
netif_tx_stop_all_queues and related functions could be used between
device allocation and registration but now only after registration.
cxgb4 has such a call before registration and crashes now. Move it
after register_netdev.

The __NS8390_init tries to start the device queue before the

This happens because the netif_start_queue sets respective bit on the dev->_tx
array which is not yet allocated.
As far as I understand the code removing the netif_start_queue from __NS8390_init
is OK, since queue will be started later on device open. Plz, correct me if I'm wrong.

The DCB credits refill quantum _must_ be greater than half the max
packet size. This is needed to guarantee that TX DMA operations
are not attempted during a pause state. Additionally, the min IFG
must be set correctly for DCB mode. If a DMA operation is
requested unexpectedly during the pause state the HW data
store may be corrupted leading to a DMA hang. The DMA hang
requires a reset to correct. This fixes the HW configuration
to avoid this condition.

(Applied over Eric's "ehea: fix use after free" patch)
Currently ehea stats are broken. The bytes counters are got from
the hardware, while the packets counters are got from the device
driver. Also, the device driver counters are resetted during the
the down process, and the hardware aren't, causing some weird
numbers.
This patch just consolidates the packets and bytes on the device
driver.

The real way to lock RX is to contend on the PCU

now just do the renames so that the next patch which changes

There was some locking for starting some parts of
RX but not for starting the PCU. Include this otherwise
we can content against stopping the PCU.
This can potentially lead to races against different
buffers on the PCU which can lead to to the DMA RX
engine writing to buffers which are already freed.

ath9k locks for starting RX but not for stopping RX. We could
potentially run into a situation where tried to stop RX
but immediately started RX. This allows for races on the
the RX engine deciding what buffer we last left off on
and could potentially cause ath9k to DMA into already
free'd memory or in the worst case at a later time to
already given memory to other drivers.
Fix this by locking stopping RX.
