Add did_interrupt() function to check if a PHY port
really caused an interrupt. This is needed in the case
of shared PHY interrupt pin configuration to stop
interrupt event processing for PHY ports which didn't
cause an interrupt.

Marvell 88E1121R Dual PHY device can be hardware-configured
to use shared interrupt pin for both PHY ports. For such
PHY configurations using shared PHY interrupt phy_interrupt()
handler will also schedule a work for PHY port which didn't
cause an interrupt.
This patch adds a possibility for PHY drivers to provide
did_interrupt() function which reports if the PHY (or a PHY
port in a multi-PHY device) generated an interrupt. This
function is called in phy_change() as phy_change() shouldn't
proceed if it is invoked for a PHY which didn't cause an
interrupt. So check for interrupt originator in phy_change()
to allow early-out.

We noticed on parisc that our broadcoms all swapped MAC addresses going
from 2.6.29 to 2.6.30-rc1:
Apr 11 07:48:24 ion kernel: eth0: Tigon3 [partno(BCM95700A6) rev 0105] (PCI:66MHz:64-bit) MAC address 00:30:6e:4b:15:59
Apr 13 07:34:34 ion kernel: eth0: Tigon3 [partno(BCM95700A6) rev 0105] (PCI:66MHz:64-bit) MAC address 00:00:59:15:4b:6e
The problem patch is:
commit 6d348f2c1e
Author: Matt Carlson <mcarlson@broadcom.com>
Date: Wed Feb 25 14:25:52 2009 +0000
tg3: Eliminate tg3_nvram_read_swab()
With the root cause being the use of memcpy to set the mac address:
memcpy(&dev->dev_addr[0], ((char *)&hi) + 2, 2);
memcpy(&dev->dev_addr[2], (char *)&lo, sizeof(lo));
This might work on little endian machines, but it can't on big endian
ones. You have to use the original setting mechanism to be correct on
all architectures.
The attached patch fixes parisc.

Fix a zero address hole bug in the bonding arp_ip_target list
that was causing the bond to ignore ARP replies (bugz 13006).
Instead of just setting the array entry to zero, we now
copy any additional entries down one slot, putting the
zero entry at the end. With this change we can now have
all the loops that walk the array stop when they hit a zero
since there will be no addresses after it.
Changes are based in part on code fragment provided in kernel:

This patch removes the sysfs entry num_vfs which was added to support
enabling pci virtual functions for 82576.
To prevent VFs from loading automatically a module parameter "max_vfs" was
added so that the number of VFs per PF can be limited. This is especially
useful when 4 or more 82576 ports are on the system because otherwise to
load all VFs would result in 8 interface per physical port.

This adds an igbvf driver to handle virtual functions provided by the
igb driver when SR-IOV has been enabled. A virtual function is a
lightweight pci-e function that supports a single queue and shares
resources with the 82576 physical function contained within the igb
driver.
To spawn virtual functions from the igb driver all that is needed is to
enable CONFIG_PCI_IOV and have an 82576 Ethernet adapter on a system that
supports SR-IOV in the BIOS. The virtual functions will appear after the
interface is loaded.
