Even though ebtables uses xtables it still requires targets to
return EBT_CONTINUE instead of XT_CONTINUE. This prevented
xt_AUDIT to work as ebt module.

Upon Jan's suggestion, use a separate struct xt_target for
NFPROTO_BRIDGE having its own target callback returning
EBT_CONTINUE instead of cloning the module.

netback is the host side counterpart to the frontend driver in
drivers/net/xen-netfront.c. The PV protocol is also implemented by
frontend drivers in other OSes too, such as the BSDs and even Windows.

The patch is based on the driver from the xen.git pvops kernel tree but
has been put through the checkpatch.pl wringer plus several manual
cleanup passes and review iterations. The driver has been moved from
drivers/xen/netback to drivers/net/xen-netback.

One major change from xen.git is that the guest transmit path (i.e. what
looks like receive to netback) has been significantly reworked to remove
the dependency on the out of tree PageForeign page flag (a core kernel
patch which enables a per page destructor callback on the final
put_page). This page flag was used in order to implement a grant map
based transmit path (where guest pages are mapped directly into SKB
frags). Instead this version of netback uses grant copy operations into
regular memory belonging to the backend domain. Reinstating the grant
map functionality is something which I would like to revisit in the
future.

Note that this driver depends on 2e820f58 "xen/irq: implement
bind_interdomain_evtchn_to_irqhandler for backend drivers" which is in
linux next via the "xen-two" tree and is intended for the 2.6.39 merge
window:
        git://git.kernel.org/pub/scm/linux/kernel/git/konrad/xen.git stable/backends
this branch has only that single commit since 2.6.38-rc2 and is safe for
cross merging into the net branch.

When the bonding module is loaded, it creates bond0 by default.
Then, when attempting to create bond0, the following messages
are printed to syslog:

    kernel: bonding: bond0 is being created...
    kernel: bonding: Bond creation failed.

Which seems to indicate a problem, when in reality there is no
problem.  Since the actual error code is passed down from bond_create,
make use of it to print a bit less ominous message:

    kernel: bonding: bond0 is being created...
    kernel: bond0 already exists.

Bringing up a bond interface with all network cables disconnected
does not properly set the interface as DOWN because the call to
netif_carrier_off occurs too early in bond_init.  The call needs
to occur after register_netdevice has set dev->reg_state to
NETREG_REGISTERED, so that netif_carrier_off will trigger the
call to linkwatch_fire_event.

When packets come in from a device with >= 16 receive queues
headed out a bonding interface, syslog gets filled with this:

    kernel: bond0 selects TX queue 16, but real number of TX queues is 16

because queue_mapping is offset by 1.  Adjust return value
to account for the offset.

This is a revision of my earlier patch (which did not use the
skb_rx_queue_* helpers - thanks to Ben for the suggestion).
Andy submitted a similar patch which emits a pr_warning on
invalid queue selection, but I believe the log spew is
not useful.  We can revisit that question in the future,
but in the interim I believe fixing the core problem is
worthwhile.

ECN support incorrectly maps ECN BESTEFFORT packets to TC_PRIO_FILLER
(1) instead of TC_PRIO_BESTEFFORT (0)

This means ECN enabled flows are placed in pfifo_fast/prio low priority
band, giving ECN enabled flows [ECT(0) and CE codepoints] higher drop
probabilities.

This is rather unfortunate, given we would like ECN being more widely
used.

CONFIG_SYSCTL is defined. So I have gone with the simpler though
