This patch provides the debugfs facility to the bonding driver.
The "bonding" directory is created in the debugfs root and directories of
each bonding interface (like bond0, bond1...) are created in that.

 # mount -t debugfs none /sys/kernel/debug

 # ls /sys/kernel/debug/bonding
 bond0  bond1

When hot-unplugging a vxge adapter while running, the driver's remove
routine prints warning and then stalls the calling thread.  This is due
to vxge_remove calling vxge_device_unregister to unregister the netdev
before calling flush_scheduled_work clear any pending work.  Swapping
the order of these two functions resolves the issue.

Use a workqueue to handle the device reset during a transmit timeout, as
there can be a deadlock during bringup.  Also, set the netif carrier off
before the watchdog reset is started to prevent the timeout from
reoccurring while still processing the first.

Calling pci_disable_sriov when unloading a SR-IOV physical function
driver from a host when a guest is using a virtual function from that
device can cause a host crash or VM crash.  The crash is caused by the
virtual config space no longer being present when PF is removed (due to
the pci_disable_sriov).  This can be avoided by not calling
pci_disable_sriov to disable the PCI space when shutting down the PF.
Each function in the X3100 operates independently and in this case will
operate properly in the absence of the PF.

Also, added improved logic in the detection of SR-IOV initialization.

The nf_pre_routing functions in bridging have collected two
distinct ways of returning NF_DROP over the years, inline and
via goto.  There is no reason for preferring either one.

So this patch arbitrarily picks the inline variant and converts
the all the gotos.

Also removes a redundant comment.

Various drivers are using implementations of ethtool_ops::get_link

them to use that instead.

While an interface is down, many implementations of
ethtool_ops::get_link, including the default, ethtool_op_get_link(),
will report the last link state seen while the interface was up.  In
general the current physical link state is not available if the
interface is down.

Define ETHTOOL_GLINK to reflect whether the interface *and* any
physical port have a working link, and consistently return 0 when the
interface is down.

This patch adds support in enic 802.1Qbh port profile provisioning code
to use the mac address set by IFLA_VF_MAC. For now we handle this mac as a
special case for a VM mac address sent to us by libvirt. The VM mac address
is sent to the switch along with the rest of the port profile provisioning
data. This patch also adds calls to register and deregister the mac address
during port profile association/deassociation.

We know for sure pktgen is going to write skb->data right after
*_alloc_skb, causing unnecessary cache misses.

Idea is to add a prefetchw() call to prefetch the first cache line
indicated by skb->data. On systems with Adjacent Cache Line Prefetch,
it's probably two cache lines are prefetched.

With this patch, pktgen on Intel SR1625 server with two E5530
quad-core processors and a single ixgbe-based NIC went from 8.63Mpps
to 9.03Mpps, with 4.6% improvement.
