This patch converts the au1000-eth driver to become a full platform-driver
as it ought to be. We now pass PHY-speficic configurations through
platform_data but for compatibility the driver still assumes the default
settings (search for PHY1 on MAC0) when no platform_data is passed. Tested
on my MTX-1 board.

All Alchemy development boards have external CPLDs with a few registers
in them. They all share an identical register layout with only a few
minor differences (except the PB1000) in bit functions and base
addresses.
This patch
- adds a primitive facility to initialize and use these external
registers,
- replaces all occurrences of bcsr->xxx accesses with calls to the new
functions (the pb1200 cascade irq handling code is special).
- collects BCSR register information scattered throughout the board
headers in a central place.

The netif_wake_queue() is called correctly (i.e. only on !txfull
condition) from txdone routine. So Unconditional call to the
netif_wake_queue() here is wrong. This might cause calling of
start_xmit routine on txfull state and trigger BUG_ON.
This bug does not happen when NAPI disabled. After txdone there
must be at least one free tx slot. But with NAPI, this is not
true anymore and the BUG_ON can hits on heavy load.
In this driver NAPI was enabled on 2.6.33-rc1 so this is
regression from 2.6.32 kernel.

The temperature and voltage limits currently set on these boards are
too conservative and will cause the driver to stop the net device
erroneously in some systems.
Based on a review of the chip datasheets and advice from the designer
of these boards:
- Raise the maximum board temperatures to the specified maximum ambient
temperatures for their PHYs plus the expected temperature bias of the
board
- Raise the maximum controller temperature to 90 degrees
- Lower the minimum temperatures to 0 degrees
- Widen the voltage tolerances to at least +/- 10%

The HT extension channel settings require priv->staging_rxon.channel to be
accurate. However, iwl_set_rxon_ht was being called before iwl_set_rxon_channel
and thus HT40 could be broken unless another call to iwl_mac_config came in.
This problem was recently introduced by "iwlwifi: Fix to set correct ht
configuration"
The particular setting in which I noticed this was monitor mode:
iwconfig wlan0 mode monitor
ifconfig wlan0 up
./iw wlan0 set channel 64 HT40-
#./iw wlan0 set channel 64 HT40-
tcpdump -i wlan0 -y IEEE802_11_RADIO
would only catch HT40 packets if I issued the IW command twice.
From visual inspection, iwl_set_rxon_channel does not depend on
iwl_set_rxon_ht, so simply swapping them should be safe and fixes this problem.

From: Steve Hodgson <shodgson@solarflare.com>
Commit 357d46a17e54c9a87e0e6ef3930ff4ab2d232b81 "sfc: QT202x: Remove
unreliable MMD check at initialisation" broke initialisation of the
SFE4002. efx_mdio_reset_mmd() returns a positive value rather than 0
on success. The above commit causes this value to be propagated up
by qt202x_reset_phy(), which is treated as a failure by its callers.
Change qt202x_reset_phy() to return 0 if successful.
The PCI layer treats >0 as "fail, but please call remove() anyway",
which means that unloading the driver would cause a crash. Add a
WARN_ON() on the failure path of efx_pci_probe() to provide early
warning if there are any other cases where we do this.

This patch fixes two potential races in the velocity driver:
* Move the ACK and error handler to the interrupt handler. This fixes a
potential race with shared interrupts when the other device interrupts
before the NAPI poll handler has finished. As the velocity driver hasn't
acked it's own interrupt, it will then steal the interrupt from the
other device.
* Use spin_lock_irqsave in velocity_poll. In the current code, the
interrupt handler will deadlock if e.g., the NAPI poll handler is
executing when an interrupt (for another device) comes in since it
tries to take the already held lock.
Also unlock the spinlock only after enabling the interrupt in
velocity_poll.
The error path is moved to the interrupt handler since this is where the
ISR is checked now.

This change corrects an issue that will cause false hangs when using either
82575 or 82580 in legacy interrupt mode. The issue is caused when there is
a slow traffic flow and an "ethtool -r" is executed while using legacy or
MSI interrupts. MSI-X is not affected by this issue due to the fact that
we were already reconfiguring the vectors after reset.
If possible it would be best to push this for net-2.6 since it is resolving
a bug but if that is not possible then net-next-2.6 will be fine.

Commit c7ab5ef9bcd281135c21b4732c9be779585181be entitled "b43: implement
short slot and basic rate handling" reduced the transmit throughput for
my BCM4311 device from 18 Mb/s to 0.7 Mb/s. The basic rate handling
portion is OK, the problem is in the short slot handling.
Prior to this change, the short slot enable/disable routines were never
called. Experimentation showed that the critical part was changing the
value at offset 0x0010 in the shared memory. This is supposed to contain
the 802.11 Slot Time in usec, but if it is changed from its initial value
of zero, performance is destroyed. On the other hand, changing the value
in the MMIO register corresponding to the Interframe Slot Time increased
performance from 18 to 22 Mb/s. A BCM4306/3 also shows dramatic
improvement of the transmit rate from 5.3 to 19.0 Mb/s.
Other changes in the patch include removal of the magic number for the
MMIO register, and allowing the slot time to be set for any PHY operating
in the 2.4 GHz band. Previously, the routine was executed only for G PHYs.

Commit 37e8273cd30592d3a82bcb70cbb1bdc4eaeb6b71 ("usbnet: Set link down
initially for drivers that update link state") changed the initial link
state in cdc_ether and other drivers based on the understanding that the
devices they support generate link change interrupts. However, this is
optional in the CDC Ethernet protocol, and two users have reported in
<http://bugzilla.kernel.org/show_bug.cgi?id=14791> that the link state
for their devices remains down. Therefore, revert the change in
cdc_ether.

The convention for API functions in kernel is to return errno value;
bond_open would return -1 if alb setup failed. The only reason that
could happen is if kmalloc() failed.

Call ixgbe_copy_dcb_cfg() earlier in the ixgbe_dcbnl_set_all() so that
we can learn if this is going to fail as early as possible. Previously,
ixgbe_down or ixgbe_close were being called before this check and the
IXGBE_RESETTING bit was being set and cleared. Worse if this failed
the corresponding ixgbe_up/ndo_open would not called.
