Update the version number for the bonding module.  Since we've just
added a significant new feature (sysfs support), bump the major number.

This large patch adds sysfs functionality to the channel bonding module.
Bonds can be added, removed, and reconfigured at runtime without having
to reload the module.  Multiple bonds with different configurations are
easily configured, and ifenslave is no longer required to configure bonds.

The sysfs interface can create bonds at runtime, so we need a separate
function to do this, instead of just doing it in the module init code.

The sysfs code needs access these functions, so make them
not static, and move the protos to the header file.

This should resolve http://bugzilla.kernel.org/show_bug.cgi?id=5519

The current feature computation loses bits that it doesn't know about,
resulting in an inability to add VLANs and possibly other havoc.
Rewrote function to preserve bits it doesn't know about, remove an
unneeded state variable, and simplify the code.

	This patch removes backwards compatibility for old ifenslave
binaries (ifenslave prior to verison 1.0.0).

	I did not similarly modify ifenslave itself; with sysfs on the
horizon, I don't see that as being worthwhile.

This change allows a bonding device to inherit the "zero-copy"
features of its slave devices.

It was inspired by a couple of previous postings on this topic:
http://marc.theaimsgroup.com/?l=bonding-devel&m=111924607327794&w=2
http://marc.theaimsgroup.com/?l=bonding-devel&m=111925242706297&w=2
and it's largely a combination of the patches that appear in those
emails.

Add support for alternate slave selection algorithms to bonding
balance-xor and 802.3ad modes.  Default mode (what we have now: xor of
MAC addresses) is "layer2", new choice is "layer3+4", using IP and port
information for hashing to select peer.

Originally submitted by Jason Gabler for balance-xor mode;
modified by Jay Vosburgh to additionally support 802.3ad mode.  Jason's
original comment is as follows:

The attached patch to the Linux Etherchannel Bonding driver modifies the
driver's "balance-xor" mode as follows:

      - alternate hashing policy support for mode 2
        * Added kernel parameter "xmit_policy" to allow the specification
          of different hashing policies for mode 2.  The original mode 2
          policy is the default, now found in xmit_hash_policy_layer2().
        * Added xmit_hash_policy_layer34()

This patch was inspired by hashing policies implemented by Cisco,
Foundry and IBM, which are explained in
Foundry documentation found at:

Add support for generating gratuitous ARPs in bonding

tagging the ARPs as needed.

Initial git repository build. I'm not bothering with the full history,
even though we have it. We can create a separate "historical" git
archive of that later if we want to, and in the meantime it's about
3.2GB when imported into git - space that would just make the early
git days unnecessarily complicated, when we don't have a lot of good
infrastructure for it.

Let it rip!
