Newer VPD datablocks can exceed the size the tg3 driver is traditionally

Occasionally, when the network cable is removed after a successful

tg3 devices will need to know exactly what function number they are so
that they can communicate their status to the other functions. In a KVM
environment, the function number of a device presented by the kernel
might not be the true function number, so an alternative method to
determine the function number is needed.
This patch used to contain an implementation for the alternative method,
but recently we discovered a hardware bug that renders it incorrect.
While new method is not yet known, it is still useful to consolidate the
code that determines the PCI function to one location and use the
results throughout the code.

Currently pci_set_power_state() does not return useful return codes for
transitions to the D0 power state. If a device refuses to go into D0,
the PCI layer issues a warning but returns success.
Entering into D0 is a requirement for correct operation of tg3 devices
though. If the PCI layer should be changed to return an error code for
this type of failure, the tg3 driver would be interested in catching it
and reacting to it. This patch makes the necessary modifications.

call their own ethtool get_settings()/mii_ethtool_gset(). The changes
