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:

The driver is currently dumping a message in the log about failing to
allocate vf data when max_vfs is equal to 0.  This change makes it so the
error message is only displayed if we set max_vfs to a non zero value.

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.
