The only user of the net_device->last_rx field is bonding.
This patch adds a conditional update of last_rx to the bonding special
logic in skb_bond_should_drop, causing last_rx to only be updated when
the ARP monitor is running.

	This frees network device drivers from the necessity of
updating last_rx, which can have cache line thrash issues.

This patch refines the phylib support in the tg3 driver.  The patch does
the following things :

* Rename tg3_mdio_config() to tg3_mdio_config_5785().  The 5785 will be
  the only device that will use it so the name might as well reflect
  that.
* Fix a memory leak if mdiobus_register() fails.
* Add code to deal with phy device detection failures.
* Add code to correct the supported list of phy features based on the
  MAC <=> PHY interface.

Commit 12dac075 ("tg3: adapt tg3 to
use reworked PCI PM code") introduced the new PCI PM API to the tg3
driver.  The patch was understandably conservative, so this patch
elaborates on that work.

The patch starts by creating a single point in tg3_set_power_state()
to decide whether or not to enable WOL.  The rest of the code in
tg3_set_power_state() was then pivoted to use the result of this
decision.

The patch then makes sure the device is allowed to wakeup before
reporting whether or not WOL is currently enabled.  The final hunks of
the patch consolidate where the WOL capability and WOL enabled flags
are set to a single location.

DASH firmware runs on the APE side of the chip, but it requires a few MAC
to be programmed correctly.

When WOL is enabled and management firmware is disabled, incoming
packets are evaluated and discarded at the chip's rule processor.
When management firmware is enabled, the hardware must be informed that
there are agents further up the stack that still use the incoming
frames.  Normally management firmware will configure the MAC correctly
on its own, but there can be cases where the setting could get clobbered
by the driver.  The first hunk of this patch preserves this setting.

The second hunk of this patch wipes out the driver present signature of
the APE memory space.  By doing so, the DASH firmware can assume
driver absent behavior.

This patch replaces the existing APE register mapping code with a call
to pci_ioremap_bar().  The code that maps the main device register space
did not undergo a similar change because the information derived from
the pci_resource_start() and pci_resource_len() is still used to
populate the (optional) mem_start and mem_end netdevice members.
Replace hardcoded constants where appropriate.

This eliminates the following often-generated warning from my 64 bit
Opteron SMP test stand:

	eth0: too many iterations (6) in nv_nic_irq

According to the web, the problem is that the forcedeth driver has a
too-low value for max_interrupt_work.  Grepping the kernel I see that
forcedeth has the second lowest value of all ethernet drivers (ie, 6).
Most are in the 20-40 range.  So this patch increases this a bit, from 6
to 15 (at 15 forcedeth becomes the driver with third-lowest
max_interrupt_work value).

My test stand, which used to print out the above warnings repetitively
whenever it was under heavy net load, no longer does so.
