- Add restriction for ESB2 to MTU size <=9216
- Removed FIFO errors which were not being used
- Fixed issues with loopback
- Power management change for saving state and config space
- WA to disable recieves and reset device on link loss. Reset needed to be done outside the interrupt context - modified existing tx_timeout_task

A recent patch attempted to enable more efficient memory usage by using
only 2kB descriptors for jumbo frames. The method used to implement this
has since been commented upon as "illegal" and in recent kernels even
causes a BUG when receiving ip fragments while using jumbo frames.
This patch simply goes back to the way things were. We expect some
complaints due to order 3 allocations failing to come back due to this
change.

Remove Message Signaled Interrupt support (for 2.6.16).
MSI is inherently edge-triggered and that is incompatiable (without more
work) with NAPI.
In future, will replace with smarter lockless-IRQ handling like
tg3.c

These messages end up polluting logs when things like NetworkManager or
wpa_supplicant are controlling the driver. They aren't really that
useful, and no other drivers output messages like this when the user
fiddles with encryption keys. Users can use iwconfig and other
wireless-tools methods to determine and change the current transmit key
if they wish to do so manually. Therefore, remove the messages.

- check that the device is up before it is enabled again;
- the descriptor ring indexes must be set to zero before
cp_init_hw() is issued. Add a nice comment to remember
that skb allocation failure is still not handled.

velocity_rx_refill() only replenishes the descriptor entries which
belong to the CPU. It works great in the Rx path but the driver must
ensure that all the descriptors are freed before velocity_rx_refill()
is used in velocity_change_mtu(). The patch resets the Rx descriptors
in velocity_free_rd_ring().

Some Sun parts don't have PCI_VENDOR_ID_SUN in the subsystem
vendor ID. So add another fallback test, which is the name
of the OBP firmware device tree node. If it's a Sun part we'll
get "network", else it will be named "ethernet".

Fix two bugs in the WoL implementation of sis900. The first causes
hangs on some system on driver load, the second causes troubles
when disabling WoL support. Both fixes are one liner and really
simple.

drivers/net/tlan.c compiles with CONFIG_PCI=n only with a warning and
due to the dead code elimination of gcc.
Additionally, this fixes the only compile error I found with

flag on i386.

Fix a race in the receive NAPI, irq handling. The interrupt clear and the

rtl8169_hw_start() requires that the descriptor ring indexes be
set to zero. Let a deferred invocation of rtl8169_reset_task()
handle it. Enabling a few power management bits will not hurt
either.
suspend/resume is issued with irq on: the spinlock do not need
to save the irq flag.

Need to avoid race in updating IRQ mask. This can probably be replaced

To avoid problems with PCI config access without ACPI (or busted ACPI tables),
use the device's window into PCI config space.
I know this probably will upset the purists, but I would rather have users
than ACPI testers. It also generates less code.

Need to force a transmit coalesce timer restart after processing
transmit packets. Otherwise, can get transmit status after last
update and chip doesn't send the next one.
Can go with the chip defaults for coalescing timers, except for
Tx timer which needs to be bigger.

Don't allow coalescing values to be bigger than the transmit ring.
Since if you set them that big, the interrupt never happens and driver
livelocks.
