tg3: Disable TSS also during tg3_close()

The TSS flag needs to be turned off during tg3_close().  If the device
fails to allocate more than one MSI-X vector the next time the device is

tg3: Add 5784 ASIC rev to earlier PCIe MPS fix

tg3 commit e7126997342560533317d8467e8516119ebcbd21 entitled
"tg3: Preserve PCIe MPS setting for new devs" attempted to ensure the
PCIe link negotiated Maximum Payload Size (MPS) setting was 128 bytes
for all devices that didn't support higher speeds.  The 5784 device was
mistakenly added to this list when it shouldn't have.  This patch
removes the 5784 ASIC rev devices from that list.

Revert "mac80211: fix sw scan bracketing"

This reverts this commit. While in theory the change is
correct the patch does not address current assumptions made
by some drivers, one which is definitley affected is ath9k.

Prior to this change the scan complete callback would be
called after we returned to the home channel and configured
the hardware RX filters. After this change we call the scan
complete callback prior to both the hw config and the config
filter. At least for ath9k this breaks quite a few assumptions
on the callback, leading to disconnects to the AP after every scan
making the driver pretty useless on STA mode. The goal behind
this commit was to address the now understood spurious warnings
from ath9k and mac80211_hwsim on scanning on two wiphys at the
same time but we have now supressed these and will address this
issue in the next kernel release.

When fixing this for good next we must first review the other
driver's dependence on this logic and perhaps consider removal
of the scan complete callback all together.

ks8842: Support DMA when accessed via timberdale

This patch adds support for RX and TX DMA via the DMA API,
this is only supported when the KS8842 is accessed via timberdale.

There is no support for DMA on the generic bus interface it self,
a state machine inside the FPGA is handling RX and TX transfers to/from
buffers in the FPGA. The host CPU can do DMA to and from these buffers.

The FPGA has to handle the RX interrupts, so these must be enabled in
the ks8842 but not in the FPGA. The driver must not disable the RX interrupt
that would mean that the data transfers into the FPGA buffers would stop.

The host shall not enable TX interrupts since TX is handled by the FPGA,
the host is notified by DMA callbacks when transfers are finished.

For 802.3 frame format with LLC or LLC-SNAP, when set the ACS
bit, the HW strips both PAD and FCS.
The FL bits, in the RDES0, actually represents the frame length
already stripped.
This patch fixes this logic within the device driver that
erroneously removed 4byte from 802.3 frames already stripped
corrupting the payload.

stmmac: fix timer setup when use dual mac Kconfig

The driver erroneously sets the tmrate to zero when the
TMU initialisation fails. This actually generates problems
while using the dual GMAC configuration.

With this patch, enabling both the dual gmac and the timer
optimisation, the first interface opened will use the tmu
channel 2, the second one won't be able to use the timer but
will continue to work without mitigating the interrupts by
using the external timer (i.e. TMU channel 2).

rt2500usb: disallow to set WEP key with non zero index

On our hardware (050d:7050 Belkin Components F5D7050 Wireless G Adapter),
setting any WEP key with non zero index, cause rx frames corruption.

Note: perhaps (I did not check) this can be fixed differently - by using
hw_key_idx the same as true MAC key index. But according to the comment in
rt2x00mac_set_key():

"the hardware requires keys to be assigned in correct order (When key 1
is provided but key 0 is not, then the key is not found by the hardware
during RX)"

this will be quite problematic. Since WEP should not be used, disabling
hardware crypto offload for it will not hurt much. Beside static
one key WEP will still be offloaded.
