The forcedeth driver uses the legacy PCI power management, so it has
to do PCI-specific things in its ->suspend() and ->resume() callbacks
and some of them are not done correctly.
Convert forcedeth to the new PCI power management framework and make
it let the PCI subsystem take care of all the PCI-specific aspects of
device handling during system power transitions.
Tested with nVidia Corporation MCP55 Ethernet (rev a2).

This patch is to add mx28 dual fec support. Here are some key notes
for mx28 fec controller.
- The mx28 fec controller naming ENET-MAC is a different IP from FEC
used on other i.mx variants. But they are basically compatible
on software interface, so it's possible to share the same driver.
- ENET-MAC design on mx28 made an improper assumption that it runs
on a big-endian system. As the result, driver has to swap every
frame going to and coming from the controller.
- The external phys can only be configured by fec0, which means fec1
can not work independently and both phys need to be configured by
mii_bus attached on fec0.
- ENET-MAC reset will get mac address registers reset too.
- ENET-MAC MII/RMII mode and 10M/100M speed are configured
differently FEC.
- ETHER_EN bit must be set to get ENET-MAC interrupt work.

The following commit made a fix to use fec_enet_open/fec_enet_close
over fec_enet_init/fec_stop for suspend/resume, because fec_enet_init
does not allow to have a working network interface at resume.

net/fec: fix pm to survive to suspend/resume
This fix works for i.mx/mxc fec controller, but fails on mx28 fec
which gets a different interrupt logic design. On i.mx fec, interrupt
can be triggered even bit ETHER_EN of ECR register is not set. But
on mx28 fec, ETHER_EN must be set to get interrupt work. Meanwhile,
MII interrupt is mandatory to resume the driver, because MDIO
read/write changed to interrupt mode by commit below.

The "index" becomes legacy since fep->pdev->id starts working
to identify the instance.
Moreover, the call of fec_enet_init(ndev, 0) always passes 0
to fep->index. This makes the following code in fec_get_mac buggy.
/* Adjust MAC if using default MAC address */
if (iap == fec_mac_default)
dev->dev_addr[ETH_ALEN-1] = fec_mac_default[ETH_ALEN-1] + fep->index;
It may be the time to remove "index" and use fep->pdev->id instead.

Fallback on the local-mac-address prom property if the Cassini device
does not have an address programmed in the VPD ROM. This uses the same
technique as implemented by the sungem driver.
The problem was reported by Frans van Berckel using Debian kernel 2.6.34-7
on Sun Fire V440. udev was assigning a new eth<n> device name on each reboot
because the cassini driver was using a random MAC address.
Fix tested on 2.6.34-7 and 2.6.37 Sun Fire V440. Compile tested against
2.6.36 davem/sparc-2.6.git
