This patch simplifies the logic and locking in sungem significantly:
- LLTX is gone, all private locks are gone, mutex is gone
- We don't poll the PHY while the interface is down
- The above allowed me to get rid of a pile of state flags
using the proper interface state provided by the networking
stack when needed and overall simplify the driver a lot
- Allocate the bulk of RX skbs at init time using GFP_KERNEL
- Fix a bug where the dev->features were set after register_netdev()
- Added GRO while at it

Some Fresco Logic hosts, including those found in the AUAU N533V laptop,
advertise MSI, but fail to actually generate MSI interrupts. Add a new
xHCI quirk to skip MSI enabling for the Fresco Logic host controllers.
Fresco Logic confirms that all chips with PCI vendor ID 0x1b73 and device
ID 0x1000, regardless of PCI revision ID, do not support MSI.
This should be backported to stable kernels as far back as 2.6.36, which
was the first kernel to support MSI on xHCI hosts.

Intel EG20T PCH has UART device which is compatible with 8250.
Currently, with general configuration, the PCH UART driver is not loaded
but 8250 standard driver is loaded. Therefore, in case of using PCH
UART driver, need to disable 8250 pci function. However, this procedure
is not best solution. This patch, in 8250_pci, if the device is the PCH
or the family IOH, '-ENODEV' is returned. As a result, disabling
8250-pci processing becomes unnecessary.

xHCI controllers respond to a Reset Device command when the Slot is in the
Enabled/Disabled state by returning an error. This is fine on other host
controllers, but the Etron xHCI host controller returns a vendor-specific
error code that the xHCI driver doesn't understand. The xHCI driver then
gives up on device enumeration.
Instead of issuing a command that will fail, just return. This fixes the
issue with the xhci driver not working on ASRock P67 Pro/Extreme boards.
This should be backported to stable kernels as far back as 2.6.34.

Some of the recently-added cpu_to_leXX and leXX_to_cpu made things somewhat
messy; this patch neatens some of these areas, removing unnecessary casts
in those parts also. In some places (where Y & Z are constants) a
comparison of (leXX_to_cpu(X) & Y) == Z has been replaced with
(X & cpu_to_leXX(Y)) == cpu_to_leXX(Z). The endian reversal of the

The call to flush_writes() in context_stop() is superfluous because
another register read is done immediately afterwards.
The call to flush_writes() in ar_context_run() does not need to be done
individually for each AR context, so move it to ohci_enable(). This
also makes ohci_enable() clearer because it no longer depends on a side
effect of ar_context_run() to flush its own register writes.
Finally, the setting of a context's wake bit does not need to be flushed
because neither the driver logic nor the API require the CPU to wait for
this action. This removes the last MMIO reads from the packet queueing
code paths.

In certain circumstances, we can get an oops from a torn down device.
Most notably this is from CD roms trying to call scsi_ioctl. The root
cause of the problem is the fact that after scsi_remove_device() has
been called, the queue is fully torn down. This is actually wrong
since the queue can be used until the sdev release function is called.
Therefore, we add an extra reference to the queue which is released in
sdev->release, so the queue always exists.

Currently the DM9000 driver requests the primary interrupt before it
resets the chip and puts it into a known good state. This means that if
the chip is asserting interrupt for some reason we can end up with a
screaming IRQ that the interrupt handler is unable to deal with. Avoid
this by only requesting the interrupt after we've reset the chip so we
know what state it's in.
This started manifesting itself on one of my boards in the past month or
so, I suspect as a result of some core infrastructure changes removing
some form of mitigation against bad behaviour here, even when things boot
it seems that the new code brings the interface up more quickly.
