It turns out that copying a 16-byte area at ~800k times a second
can be really expensive :) This patch redesigns the frags GRO
interface to avoid copying that area twice.

The two disciples of the frags interface have been converted.

The recent changes of the PCI PM core allow us to simplify the
suspend and resume handling in a number of device drivers, since they
don't need to carry out the general PCI PM operations, such as
changing the power state of the device, during suspend and resume any
more.

Simplify the suspend and resume callbacks of r8169 using the
observation that the PCI PM core can take care of some operations
carried out by the driver.

Additionally, make the shutdown callback of r8169 only put the device
into a low power state if the system is going to be powered off
(kexec is known to have problems with network adapters that are put
into low power states on shutdown).

This patch has been tested on MSI Wind U100.

This patch does two things:
1) On 82599, the PHY is emedded in the MAC.  On 82598, the SFP+ NIC has an external PHY.  The reset in the SFP+ setup patch for 82598 is unnecessary on 82599, and adds extra dead time to device initialization.  This removes that PHY reset for 82599 only.

2) On 82599, the SFP+ modules are multispeed fiber modules (10G/1G).  We need to make sure to identify them properly for the remaining init sections to properly set them up.

When PHY operations are determined, the PHY must be identified.  This
identification causes bus access, and should be contained within its own
routines.  This also helps the 82599 PHY init paths for both SFP+ and
KX/KX4 devices to be easier to maintain.
